Door Closers and Controls
Generally door closers are found on fire doors where self-closing is a legal requirement, and elsewhere where it is convenient to ensure that doors stay shut. They range from economic uncontrolled door slammers to sophisticated models that operate only in emergencies and can be adjusted for changing conditions. SDS are able to provide overhead door closers that meet the current DDA requirements for door opening forces.
Concealed door closers are often preferred in domestic and high end applications. Jamb mounted versions range from the BSEN1154 conforming adjustable Powermatic, to the mid range Perkomatic down to the original Perko door closer. Overhead concealed closers combine the efficiency of overhead closers with the aesthetics associated with concealed closers and consequently are often found in hotels and quality developments. Various finishes can be applied to the joining arm and overhead channel to special order
Overhead door closers are probably the most efficient and popular means of closing a door and here we have a selection to cover most door sizes. SDS overhead door closers are normally supplied with push and pull side fittings for convenience with standard, hold open and swing-free variants.
Floor springs are useful in high traffic areas and/or where the doors are required to swing both ways double acting. These can also be used to swing gib concealed doors, usually as a single acting variant. Electro-magnetic hold open options are also available to special order.
Floor pivots perform similar tasks to floor springs but are not self closing, so strictly speaking are not door controls.
Miscellaneous closers and accessories covers various non-standard closing devices along with door selectors and friction stays.
Dorgards are stand-alone door holders that release the door upon hearing a fire alarm, allowing a separately fitted door closer to close the door. These allow for wire free installation.
Emergency exit panic hardware including panic bolts and panic bars should be capable of being easily and immediately opened from the inside to facilitate prompt escape from fire. See our range here.
