The SASHSTOP Window Jammer is a simple yet highly effective window security device designed to provide additional protection to uPVC and standard casement windows. Installed neatly beneath your existing window handle, it reinforces the locking point to help prevent forced entry without the need for drilling or permanent modification.
Ideal for homeowners, landlords, housing providers and commercial properties, the SASHSTOP Window Jammer offers an easy-to-fit, cost-effective solution to improve window security. It is particularly useful where window mechanisms may have weakened over time, where handles feel loose, or where extra reinforcement is required for peace of mind.
Because it fits most standard window handles with 43mm fixing centres, installation takes just minutes. The included self-adhesive foam pad eliminates the need for drilling, making it suitable for rented accommodation or temporary security upgrades. The jammer also features a quick-release, non-locking function, allowing windows to be opened easily when required.
In addition to enhancing security, the SASHSTOP Window Jammer can help create a tighter seal on slightly draughty windows, improving comfort and potentially reducing heat loss.
