Door Hardware

Keys and Keying

Inactive Door (of pair) Securing Hardware

Door Bolts

Surface bolts are, as their name implies, surface mounted on the inactive door. They must be manually latched/unlatched.

Manual Flush bolts are installed in the edge of the lock stile of the inactive door, so they cannot be seen when the doors are in a closed position. They must be manually latched/unlatched.

Self-latching flush bolts are installed similar to manual flush bolts. Self-latching flush bolts are typically used at the top of the door, in conjunction with an Automatic-latching flush bolt at the bottom of the door. The self-latching flush bolt must be manually unlatched, but will automatically latch when the inactive door closes.

Automatic-latching flush bolts are installed similar to manual flush bolts. Automatic-latching flush bolts are typically used at the bottom of the door, in conjunction with a Self-latching flush bolt at the top of the door. The automatic-latching flush bolt unlatches automatically when the active door opens, and latches when the active door closes.

Barrel bolts are used to secure doors, gates, and cabinet doors.

Cane bolts are used on oversized doors, or gates.

Spring bolts are used on oversized doors. The bolt is by default extended to keep the door latched at the top. To open, pull the chain to retract the bolt, when chain is released, the spring will force to bolt to extend.

Removable Mullions

Removable mullions are typically used with exit devices on openings in which require, at times, the full width of the opening. Some removable mullions are available with a keyed mortise cylinder for added security, and ease of removing the mullion.

Dummy Trim

Dummy trim is used on the inactive door of a pair to match the lockset, or exit device trim on the active door for aesthetics, and to be used as a door push/pull.

Active Door (of pair)/Single Door Securing Hardware

Locks

• Grade 1 – Heavy duty, used in high-frequency openings i.e. main entrances
• Grade 2 – Standard duty, used in moderate used openings i.e. washrooms, offices
• Grade 3 – Light duty, used in low-frequency openings i.e. apartments

Advantages of cylindrical locks are they are less expensive than mortise locks, easier and faster to install, and have key in knob, or lever features.

Mortise locks are one of the most durable types of locks available. They offer long lasting operation, and low maintenance.

Keypad locks, card reader locks, FOB reader locks are to control entry to certain areas by requiring the need to use proper credentials for the lock to open. Most of these types of locks offer audit trails to allow tracking of who has been gaining entry.

Options available for locks:

Electronic locks. Offer the capability of electronically unlocking the lock to help control ingress/egress remotely

Exit Devices

Rim mounted exit devices are installed on the face of the door. Rim devices are typically the most secure, and most cost effective type of exit device.

Mortised exit devices have a mortise lock body in the lock stile of the door, and the actuating bar is mounted on the face of the door.

Surface mounted vertical rod exit devices are typically used on pairs of doors. They are installed on the face of the door with a top and bottom rod that extends the full height of the door. At the ends of these rods are the latches that secure the door in the closed position. These devices are also offered with Less Bottom Rod configurations.

Concealed vertical rod exit devices are similar to the surface mounted exit devices , but the rods that extend the height of the door are concealed in the door, while the actuating bar is surface mounted on face of the door.

Exit device trims are offered for all exit devices as a means of operation from the pull side of the door.

Options available for exit devices:

Troubleshooting:

• Improper installation of frame/door
• Door prepared incorrectly
• Strike not installed correctly
• Incorrect strike supplied for condition
• Device not mounted level
• Vertical rods not aligned correctly
• Vertical rods not long enough due to non-standard mounting height of device
• Fasteners either too tight or loose
• Operating trim not installed properly

Cylinders

Mortise cylinders are identified by the threads on the cylinder housing allowing it to be threaded into hardware items such as mortise locks, certain exit device trims, key switches, etc., and held in place by a setscrew.

Rim cylinders are similar in appearance to a Mortise cylinder, but they do not have the threads, and have a long tailpiece which extends through the door into the latching mechanism, typically an exit device

Key-in-knob (KIK) / Key-in-lever (KIL) cylinders are typically factory installed in the knob/lever of the lockset. If needed, this cylinder can be removed, and replaced with a different keyway to suit needs.

Options available for exit devices:

Interchangeable cores. These are available for both Mortise, and Rim cylinders. The advantage of these cylinders is that the keyed portion of the cylinder, or core, can be removed with a special control key, and a new core installed without the need to disassemble the lock, or exit device.

Operating Trim

Push plates are used on doors without latching hardware to protect the door from scratches, and dirt.

Door pulls are used to provide a handle to grasp to open the door. They are referred to by their center to center dimension. Door pulls can also be provided with backing plates to help further protect the door from scratches, and dirt.

Flush pulls are used in instances when you need to pull the door open, but do not want a door pull projecting from the face of the door i.e. school gymnasium.

Pair Doors Accessories

Astragals are used to cover the gap between leaves of doors in a pair. They can either be a spilt astragal which comes in two pieces, with one piece being installed on each leaf of the opening, when the doors are in a closed position, the astragal intertwines, closing the gap. This allows both leaves to operate independently. The other option is an overlapping astragal which is one piece fixed to one leaf of the opening. This allows only the active door to be opened first, and the use of a coordinator to ensure that the inactive door closes first allowing the active door to latch into it.

Coordinators are used on pairs of doors where both leaves can be opening, but one leaf must come to a full closed position so that the active leaf can latch into the inactive leaf, securing the opening.

Closing and Controlling Devices

Closers

• Fire doors. Closing devices must be installed on all fire rated doors
• Security. Doors to secure areas must be able to close and latch
• Energy loss. Returning the door to the closed position helps reduce energy loss for air-conditioned, or heated areas
• Sound containment. Minimize sound transfer from different areas of a building
• Push/pull doors. Holding the door in a closed position for openings without a lockset or exit device i.e. public washrooms

Surface mounted door closers are the most cost effective, and effective means of controlling doors. Surface mounted closers are mounted on either side of the door.

Concealed door closers. There are three designs for concealed door closers, Floor concealed closers are mainly used for heavy/oversized doors. Concealed in door closers are used when the use of a concealed floor closer, or concealed in frame closer cannot be used. Concealed in frame closers are used when the use of a concealed floor closer, or concealed in door closer cannot be used.

Options available for door closers:

Hold open arms are used when it is desirable to have a door held open during certain parts of the day. These types of arms are not available on fire rated openings.

Stop arms or Stop and Hold arms are available so that the doors cannot be opened past a certain point.

Adapter plates, and Drop plates are frequently required in order to install a closer due to other conditions such as low clearance, other hardware, narrow stile, etc.

Electric release door closers can be used to hold open fire rated doors. These closers are integrated into the buildings fire alarm system, so that at time of a fire alarm, the closer will automatically close the door.

Troubleshooting:

• Improper installation of closer
• Incorrect closer specified for mounting type required
• Incorrect size of closer for door/conditions
• Fasteners either too tight or loose

Protective Plates

Kickplates and installed at the bottom of a door on the push side. Kickplates are undersized 1-1/2” less than the nominal door size for a single door, or 1” less than nominal size on a double door.

Mop plates are used to protect the door from vacuuming, wet-mopping, cleaning equipment, etc. and are installed at the door bottom on the pull side of the door. Mop plates are undersized 1” less than the nominal door size.

Armour plates typically measure 24” – 48” in height. They are installed on the push side of a door with large, heavy equipment moving through the opening. Note that due to the height, Armour plates may interfere with latching hardware, or lites in the door.

Door Stops & Holders

Floor mounted stops

Wall stops must have adequate wall reinforcing so that the stop is not driven through the wall material.

Overhead door stops are much more durable than either the floor mounted, or wall mounted stops. They can be used on doors with high-frequency use, or when the use of floor mounted, or wall mounted is impractical i.e. closet doors swinging into a corridor

Overhead door holders are very similar to Overhead door stops, but with the added feature of holding the door in an open position. Overhead door holders cannot be used on fire rated openings.

Kick-down door holders are an inexpensive and practical way to hold open a door. Kick-down door holders cannot be used on fire rated openings.

Weatherstripping

Thresholds have several uses i.e. providing a seal for a door sweep to butt against, transition from different flooring on each side of the opening, transition from different floor heights on each side of the opening. Note that for a barrier free accessible opening that maximum height allowed for a threshold is ½”

Gasketing (weatherstrip) is used to help create a better seal to help with energy conservation, softening of sound transference, dust/smoke/light control, etc.

Door sweeps are installed to create a seal at the door bottom, typically against the threshold, to help with energy conservation, softening of sound transference, dust/smoke/light control, etc.

Automatic door bottoms are used to help create an exception seal. When the door closes, the activator rod is depressed against the door jamb, forcing the door bottom seal to drop, and create a seal along the floor/threshold. When the door opens, the door bottom seal is retracted by an internal spring. Automatic door bottoms come in three types: surface mounted, semi-mortised, and mortised, the latter two require special door preparations.
