CRL PTH311 Glass-Mounted Latch (SKU: PTH311MBL) is a heavy-duty glass door latch designed for commercial and residential tempered glass doors.

• Glass-mounted design—no door drilling beyond required holes
• Durable 304 stainless steel—ideal for high-traffic, coastal, or humid environments

Two 1-7/8" (48 mm) holes

Note for double door applications:
