The Old Style with pins and the New Style with alligator teeth are not interchangeable.

This Roto Multipoint Lock Gearbox is designed exclusively for use with current-style multipoint locks. It is incompatible with older Roto locks.

The new style gearbox features alligator teeth at the top and bottom, allowing for quick and secure attachment to the upper and lower extensions. Older-style locks, by contrast, use pins for connection.

For visual reference, see additional pictures to ensure proper identification and compatibility.
