Frequently Asked Questions

What does 'double spindle' mean for this lock case?

A double spindle configuration means the lock case has two spindle positions at different PZ measurements (92mm and 62mm), allowing it to work with specific handle and cylinder arrangements.

Can I use unsprung handles with this lock case?

No, this is an unsprung gearbox, so your handles must have a built-in spring cassette. Using unsprung handles will cause them to droop after operation.

How do I reverse the latch handing on this lock case?

Undo the screw in the latch to remove it, reverse the latch orientation, reinsert it, and replace the screw.
