Designed to clip fit. They add additional strength and with their unique “reverse ramp” design allow for windows to open smoothly.

Run-Up Blocks

Our Run-Up Blocks are designed to clip fit. They are also engineered with sturdy side walls to give additional strength – a must in BS7950 security tests where they work as anti-lift devices.

Our Blocks have passed these tests with several different PVC-U systems. The design also Includes a unique ‘reverse ramp’ so windows open as smoothly as they close and even has a detail so that drainage is not impeded.
