Product Description
Multi-position hook-style window restrictor, compatible with both drilling and nail-free adhesive installation methods, available in two sizes (long and short); limits window opening to allow ventilation while preventing children from falling out of windows, and provides wind-resistant stability; compatible with aluminum alloy and PVC-coated steel inward- and outward-opening windows.
Product Details
Innovative hook-type adjustment mechanism: Less prone to slipping out of place compared to traditional U-shaped slots; multiple adjustment levels allow for free regulation of the window opening angle, balancing ventilation with safety protection.
Dual Installation Options: Can be secured with screws through drilled holes or attached using nail-free adhesive without drilling, protecting the window frame’s finish and meeting various home renovation needs.
Universal design compatible with inward-opening, outward-opening, and bottom-hung casement windows.
Made of sturdy, durable metal with a rust-resistant spray-coated finish; resists deformation and loosening during daily use. Each set includes a locking rod, base, and matching installation screws.
After installation with nail-free adhesive, allow 48 hours for full curing before use. Clean the window frame surface before application to ensure a secure bond.
