Sash Window Weights

What is a Sash Weight?

A sash window weight is used to counter-balance the weight of a sliding sash in a sash window and thus hold it in position at any height.

Steel sash weights were designed by Mighton in 1985. As square steel weights are denser than their round cast iron counterparts, you can squeeze more weight into your window box allowing you to compensate for heavier sashes.

Mighton also developed the format that lead sash weights are manufactured to today. Namely in 600mm lengths and six section sizes.

Steel or Lead Weights?

Steel sash weights are a cheaper alternative to lead, however, sometimes lead needs to be used when there is not enough room in your box. Lead weights can easily be cut to size and have a hole running through the middle of the entire weight.
