GAL Retrofit Interlock Adapter for Type SM to Type SN Lock

Compatible with legacy GAL Type SM lock systems commonly found in Garaventa, Genesis, LU/LA elevators, and some PFlow platform lifts.
Allows replacement of obsolete SM locks with modern GAL SN lock units for continued compliance and function.

This retrofit adaptor lock contact compensates for the depth difference between GAL’s discontinued Type SM lock and the current Type SN model. By offsetting the shallower SN lock, it ensures that the new unit aligns precisely with the original lock position—eliminating the need for field modifications.

• Designed for GAL Type SN lock retrofit in SM lock applications
• Bridges depth gap between SM (deeper) and SN (shallower) locks
• Maintains original lock alignment with door hardware
• Supports continued use of older elevator systems
• Precision-machined for secure fit and stable mounting
• Standard replacement component for modernization and repair
