Crimebeater gearboxes measure 227mm high by the backset + 15mm. These gearboxes attach to their strips with three equidistant screws. The middle screw is 108mm from the top, which is also 108mm from the bottom screw.

These gearboxes all feature a deadbolt and latch. The latch is 24mm high, the deadbolt is 30mm high and the distance from the bottom of the latch to the top of the deadbolt is 72mm.

Note that the latest version has a small rectangular raised area just above the cylinder cut-out, this is to prevent manipulation of the lock gate if the handles are removed, if the new case will not go back in then enlarge the hole to allow entry.
