Step-by-step
-
Remove old handle
Open the window slightly, pop off screw covers, and undo the visible screws (usually 2 or 3). Lift the handle straight off. -
Check stack height (“A” dimension)
Place the old handle flat, measuring from the surface to the underside of the spur. This tells you your handle's stack height and ensures a snug fit. -
Confirm handing
Look at which way the spur hooks—left or right—and match that when ordering the new handle. -
Fit the replacement
Align the handle and secure it with the screws you removed (or new stainless screws). Tighten until snug. -
Test operation
Close the window and move the handle through its full range to make sure the spur engages the wedge properly.

FAQ
Handle doesn’t close flush? The stack height likely doesn’t match. Re-measure the A dimension and order the correct product.
Can I use same screw holes? Yes—unless brittle or damaged. Re-use where possible for best fit and aesthetics.
Keyed handle or plain? Most cockspur handles can be ordered keyed (matching cylinder) or non-locking for convenience or security.
