Hyjoy Window Locks 8-Pack — Diecast Vise-Grip for Horizontal & Vertical Windows, Fits 1/16" (0.16 cm) to 7/8" (2.22 cm) Rails — 1-1/2" Long Version

Durable diecast construction provides strong, long-lasting protection. These Hyjoy window locks clamp securely with a vise-style grip to window frame rails from 1/16" (0.16 cm) up to 7/8" (2.22 cm) thick, letting you ventilate while keeping the opening restricted. Note: the short model (1-3/16") is intended for windows only; for doors use the larger 1-1/2" version. Easy, tool-free setup streamlines installation and requires no permanent hardware. The jaw width and cam lever are quickly adjustable to fit most vinyl frames and to set the desired limit on horizontal sliders or single-hung vertical sashes. Built to deter intruders and stand up to severe conditions, the locks help hold windows in a ventilating position and resist hurricane winds. Travel- and rental-friendly, the non-marring grip prevents scratches and limits opening to reduce the risk of accidental falls—ideal for hotels, classrooms, rentals, and family homes. Each package includes 8 window locks; components are 99% vinyl and the diecast body in white blends unobtrusively with most decor.
