Door closers & exit hardware Door furniture Locks & cylinders Latches 26 UNION Trade catalogue An essential part in making sure a door shuts properly, door latches need to be robust and long-lasting because of how many times they will be used throughout the day. The majority of our internal door latches have been put through rigorous testing, so you can be confident they’re built to last. Plus, our latches are offered in a range of styles, so you can find the right latch to match other door fittings. Types of latches Latch: Automatically springs into the strike plate to hold the door into the closed position until the handle is operated. Bolt: The bolt can be withdrawn to allow the door to swing free, then manually thrown to secure the door. Dimensions 4 5 2 1 3 2 Backset 1 Bolt projection/throw 3 Case size 4 Height 5 Width EN 12209 Standards EN 12209 – classifies mechanically operated locks, latches and locking plates using an 11 digit coding system. Each digit refers to a particular feature of the product measured against the standard’s performance requirements. Fire door testing – fire resistance within door assemblies serves three main purposes: to restrict the initial development of the fire, to restrict the spread of the fire and to protect escape routes. Whenever fitting a latch to a fire door it must be fire door tested and fitted with an appropriate intumescent kit. How to select the right latch • What function do you require – latch or bolt? • What security level is required? • H ow far back from the door edge will the door handles be positioned? (This will determine the required back set) • What handles? Please see our handle collection • Is it a fire door?
