Protect your home with the XFORT door and window blocker with key. These security locks act as smart stoppers or restrictors and can be fitted on uPVC doors and windows that open inwards or outwards. This low-cost home security solution prevents the levering of the window sash or door leaf. For added safety, these locks help protect children from unlocking doors or windows themselves, ensuring their safety when out of your sight. They also prevent accidental unlocking from the inside and provide resistance against forced entry, deterring intruders. The sash jammer is available in a white finish, designed to blend seamlessly with your décor. It includes 1mm and 2mm packers for a secure and easy installation. The locking sash jammer features a durable locking arm that stays in place once locked with the key, offering total security. The slim design provides a sleek look that complements your home décor.
