Springs: Sash weight is supported by the appropriate strength spring.

Sash Stops: The travel of top and bottom sashes is restricted by nylon stops as shown lower left. The stops run through to head / sill to ensure that the stop stays in position when struck by the moving sash. On competitor windows the stop relies on a single fixing screw - this has been known to fail.

Friction Shoes: The spring balances are supported with adjustable friction shoes shown top left.

Friction Shoe Protection: The shoes are recessed into the bottom of the sashes. When the top sash is pulled fully down and the sash side rail runs into the sash stop - the shoe is protected from the impact.S

Shoe Adjustment: With Philips screw driver it’s possible to tighten or loosen the friction shoe as shown lower right. Turn the screw driver clockwise to tighten the shoe and anti-clockwise to loosen the shoe. Support the weight of the sashes as you adjust the shoes.

Important Note: Do NOT lubricant to the slide shoe recess (jamb) as this would have a very detrimental impact on the spring friction shoes.
