Zinc-Alloy Sliding Window Crescent Lock fastens compatible sliding sashes at the meeting rails. Its rotating zinc-alloy housing carries the SUS304 crescent hook into the keeper. Model E828-Y8285 depends on the lock base and keeper sitting on compatible planes, because an excessive height difference prevents clean entry.
Crescent Draw-In Motion
