Brolite Hexagonal Nickel Door Knobs on Black Bakelite Rose

Hexagonal solid brass door knobs with a polished nickel finish on square black bakelite back plates. Pairs of handles or knobs are complete with a 5/16" (7.9mm) square spindle so they should fit some old locks as well as new ones. You may have a 7.6mm spindle in the old lock, in which case the square hole in the lock can be filed out to 7.9mm with a sharp square file. The necessary slotted grub screws for the spindle and slotted wood screws for the plates are also supplied. The square back plate is No 6060 and the knob is No 6130. Measurements: Knob: 43mm across the flat edges (50mm at the furthest points). Back-plate: 54mm x 54mm Projection: 60mmAll our BROLITE real Bakelite pieces have been modelled on original designs from early to mid-20th century. The door knobs & handles are interchangeable on all the Brolite backplates, so you can order the parts individually if necessary.

You willl therefore need to ensure that the latch or lock used has sufficient spring capacity.
