Ironmongery

  • ESSENTIAL IRONMONGERY

    Items vital to achieve the desired level of performance of a fire door assembly’. These items include hinges, locks, latches, bolts, pivots, and self-closing devices.

    All essential ironmongery must be tested or assessed for use in the chosen door core and to the desired fire rating. Ironmongery should be CE marked and comply with relevant test standard and be suitable for the duty of use with regards to durability and cycle testing.

  • BACKSET

    Refers to the distance from the edge of the door to the spindle mechanism on the latch.

  • BUTT HINGES

    A butt hinge is a type of mechanical bearing that connects two objects together while allowing them to swing open and closed. This type of hinge is to be used to provide an attachment between two abutting surfaces such as the door and the jamb.

  • CYLINDER LOCKS

    The cylinder is an essential part of a lock, as serves to open and close the door. It generally consists of a metal cylinder into which a key is inserted to.

  • CYLINDER PULL

    A cylinder lock that works with a night latch to ensure that when you pull the door closed from the outside the night latch automatically engages with a keep in the door frame to lock the door.

  • DEAD LOCKS

    A deadlock is a type of lock that can only be unlocked using a key when in deadlock mode. Standard deadlocks have keyholes on both sides, which means if you lock the door when you are inside, you will need the key to get out.

  • DEADBOLT

    A deadbolt or deadlock is a type of lock morticed into a wooden door. Then, using a key from either side of the door, a bolt is thrown into the door frame, thus securing the door. It is distinct from a spring bolt lock because a deadbolt can only be opened by a key or handle.

  • DOOR LATCHES

    A mechanism that moves between a pre-cut hole in the door frame to hold the door in place until the handle or knob is turned to retract the latch allowing the door to be opened.

  • ESCUTCHEON

    Also known as keyhole covers, are the hardware details that surround the keyhole on a door. These are used to give a clean and neat appearance to this area plus, offer protection to the door against damage from the key.

  • EURO PROFILE

    This is an oversized keyhole shape that is designed to accommodate a Cylinder Lock rather than the key itself.

  • FACE-PLATE

    A solid or plated trim that allows a latch to pass through the edge of a door.

  • FLUSH-BOLT

    Flush bolts are used to secure the inactive leaf of a pair of doors, projecting into the frame head and into a floor strike. In this application, the active leaf would typically have a lockset which latches into a strike mounted on the edge of the inactive leaf.

  • LATCH PACKS

    These packs contain everything you need to fit your door including handles, hinges and a latch mechanism.

  • LETTER-PLATES

    Part of a letterbox. Letter plates are the plate that sit on the external part of the door to cover an aperture. They are available in polished brass, stainless brass, polished chrome, satin chrome and many other finishes. Letter plates work in conjunction with Inner tidies/flaps.

  • LOCKSET

    This simply refers to the overall locking mechanism, including the handle if it has one.

  • MORTISE LOCK

    A lock which is set within the body of a door in a recess or mortise, as opposed to one attached to the door surface.

  • MULTIPOINT LOCK

    A lock system utilising several locking points for added security and strength, typically these are operated by a single handle.

  • NIGHT LATCHES

    Sometimes referred to as a Yale lock, these are operated by a turn and key combination.

  • PULL HANDLE

    Larger than most typical handles, these are not designed for controlling a latch and simply are intended to help pull open a swinging door on a hinge. These handles work well with other accessories such as pictograms, finger plates on the alternate side and can also make use of door closers.

  • RIM LOCK

    A lock fitted into the inside surface of a door that can only be opened from the exterior, this design is commonly used on less secure doors such as internal doors.

  • SASH LOCK

    A sash lock is sometimes called a mortice sash-lock, and has a dead bolt and latch combined within a case. Sash locks are fitted into the material of a door, rather than onto the surface, and are designed to work with a pair of door handles.

  • SPYHOLE

    A small hole in a door that you can look through to see who or what is on the other side.

  • STRIKE-PLATE

    A metal plate affixed to a doorjamb that holds the door closed when the door bolt is extended into a hole, protecting the jamb against friction from the bolt.

  • THUMB-TURN / SNIB-TURN

    A thumb turn lock, sometimes also called a bathroom lock, is a simple security lock typically installed on bathroom or bedroom doors. It’s convenient because it has a mechanism that allows you to open it from the outside in case somebody locks themselves in accidentally or is otherwise unable to get out.

  • TRACK

    The track will be found in bifold and sliding doors and is often a metal track that the doors themselves slot into. The track is called as such because it resembles a train track.
