  • Available with a variety of pull handles
  • Standard or keyed alike cylinders

  • Available with access control facility
  • The ideal locks for commercial doors

Our commercial doors using the Senior system come numerous main locking options such as hook locks, latch locks and latches with electric release strikes for access control.  Our commercial door locks work with single or double action doors and a choice of key/key or key/turn cylinder.  Electric strikes work with most common buzz entry systems, keypad locks or swipe card systems.

All our commercial door locks are provided fitted to the door stiles or frames, depending on the type and work with single doors, double doors or doors with side panels. We use the leading lock brands such as Alpro, Axim, Assa Abloy and many lock brands, all designed for the narrow, standard or wide styles available with our thermal and non-thermal commercial aluminium doors.

Our range of door locks cover hook locks for single or double action doors required to stay open.  Deadlatches suit commercial doors required to latch shut every time. The design of these locks is such that they can either be operated with a key, thumb turn or suitable lever or paddle handles. Electric locks for access control doors require wiring into the building system by a qualified electrician.
