This is a very sleek, very sturdy cremone bolt fashioned from stainless steel.
The knob is vertical when locked, and horizontal when unlocked.
Right Handed model turns counter-clockwise to unlock, clockwise to lock.
Single sided operation only.
Turning the knob 90 degrees throws each rod 5/8". Sturdy rack and pinion mechanism throws rods with confidence.
The center mechanism measures 1-5/16" wide x 5-1/16" tall. The knob measures 4-5/16" tall and projects a total of 3-3/8" from mounting surface.
Set includes 2 equal length rods. Rods are 8mm or 5/16" square. Maximum retracted length is 112-1/4". Maximum extended length is 113-1/2".
There is clearance between the rods and the mounting surface of about 3/16". This feature makes for easier alignment when using angle strikes on outswinging doors and windows.
Each set is provided with 2 end guides, 2 box strikes/center guides and 2 angle strikes.
When this cremone is installed on outswinging doors/windows, the box strikes/center guides are used as center guides midway between the center mechanism and the end guides. When this cremone is installed on inswinging doors/windows or on cabinet doors, the box stikes/center guides may be used as strikes with only one end guide on each rod.
