These locking hinges join a seat to a back and hold the seat to back angle you set. The taper joint locks when it is tightened, so the angle stays put under load and does not creep on a client who pushes hard into the backrest.
The range covers left, right and paired sets, bi-angular locking hinges, and swingaway versions for clients who need the back cleared for transfers or for getting the chair into a vehicle. Slots on the plates give you fore and aft adjustment when you are setting the seat position.
They are made in black stainless steel and supplied with the bolts you need, which keeps an install tidy for a technician working on a custom seating build.
