SPINDLES-
1) Threads
a) size- our spindles are all 8mm. But we do have some threaded 7mm passage spindles in stock. (701201)
b) size- our 8mm spindle threads are 3/8"-20, this is most common historical size
c) fitment- many historical knobs will fit our spindles, but we cannot guarantee this
2) Types-
a) threaded (for Restoration products- currently used only for HOAH), and non-threaded (used on pre-attached [KP] knobs ).
b) passages and privacies use the same type split-spindle privacy- we have two types:
1) old style- screws together and has a visible post on one half (these break, and a current spindle can be substituted)
2) current style- swivel joint in middle, pop-up button to center in latch
c) dummy-
1) surface-mounted to the door with three screws, knob screws-on to hold rosette/plate in-place via Restoration
2) two different lengths (27mm-701069, and 18mm-701084), COT, STU, CRA, MIS require the shorter version (701084)
d) mortise- uses solid spindles, may fit other mortise locks, but we cannot guarantee this- some older mortise locks use 7mm
e) handleset- four different versions:
3) Lengths
a) passage- 100mm (4")
b) privacy- 100mm (4"), and 82mm (3 1/4"), ONLY old COT/STU w/o knob bushing use 82mm
c) dummy- 27mm ( 1 1/6") and 18mm (3/4")- COT, STU, CRA, MIS require the shorter version (701084)
