Patented Clamp and Brace Design

Manufactured from zinc-plated steel for maximum durability, offering more than twice the strength of aluminium alternatives.

Top Hung and Side Hung Compatibility

Suitable for top hung, side hung and externally glazed windows across uPVC, aluminium and timber frames.

Fast Setup, Faster Repairs

Sets up in seconds, enabling complete sash removal and refitting in minutes, even on complex repairs.

Expandable Accessory System

Premium Steel Construction

Manufactured from zinc-plated steel for maximum durability, offering more than twice the strength of aluminium alternatives.

Scalable Load Capacity

Increase load capability by using additional Sashmate® sets, providing confidence when working with heavier sashes.

Sashmate® Top Hung - Main Tool

Setup in seconds the Sashmate® Top Hung will make any repair simple. Use on small top vents and top hung sashes above, below and between transom bars.

Sashmate® Side Hung - Main Tool

Setup in seconds the Sashmate® Side Hung will make any repair simple. Using the Sashmate® Side Hung is simple and efficient and enables a sash to be removed and re-fitted in less than two minutes.

Top Hung Rolling Bar - Accessory

The Top Hung Rolling Bar has been developed to give additional safety and ease when repairing top hung windows. The Rolling Bar system stabilises the two independent Sashmate Top Hung tools whilst creating a rolling platform, allowing the fitter to safely and securely slide the sash in and out of the building. Perfect when working with a heavy sash, when working over an obstacle such as a kitchen sink or working on a kitchen worktop.

Top Hung Drop Set - Accessory

Use in addition to the Sashmate Top Hung when one or both of the existing window hinges are twisted and have collapsed. The Drop Set allows the Top Hung horizontal arms to fit underneath the drop side/s of the window. The Drop Set should also be used on windows fitted with oversized hinges - where a window was fitted with laminate glass units the manufacturer may have used oversized window friction stays.

Telescopic Main Rods - Accessory

The Sashmate® Telescopic Rods are used instead of the standard solid main rods, allowing the Sashmate® Top Hung into short complete openers of 650mm, where the total height of the window - between plaster and window board - is less than 1010mm. This accessory pack comes complete with 2 sets of rods. Set #1 650mm to 880mm and set #2 880mm to 1220mm. Can also be used with the Sashmate® Side Hung.
