## Description

This deadbolt lock fits standard interior and exterior doors with thicknesses from 1-3/8 in. to 1-3/4 in. making it suitable for residential entryways, bedrooms, bathrooms, kitchens, patios, and light commercial settings like offices or classrooms. Its adjustable latch extends from 2-3/8 in. to 2-3/4 in. accommodating both new installations and retrofits on existing doors. The all-metal build includes a stainless steel faceplate, a zinc-coated copper cylinder, and a zinc alloy latch for consistent strength and corrosion resistance.
