Products
Which sliding roller should I specify for my sash weight?
Choose the carriage by wheel count, not by frame size. Single wheel rollers suit light domestic sashes, the two wheel carriage spreads the load across the track for heavier panels, and the four wheel carriage is for the widest and most heavily glazed sliding doors. Send us the glazed sash weight and the track section and our team will confirm the right carriage.
What is the difference between a V-groove and a U-groove roller?
The groove profile has to match the track the sash runs on. A V-groove wheel locates on V-profile track and a U-groove wheel on U-profile track. Running the wrong profile puts the load on the wheel edge instead of the groove and wears both the wheel and the rail.
Which stainless steel grades do you use?
It depends on the product. Friction stays, friction arms, U-groove friction and track rail are SS 304. The 1, 2 and 4 wheel roller carriages, euro cylinders and lock bodies are supplied with stainless bodies. Each product page lists the finish the catalogue states for that item.
Do you supply friction stays for uPVC as well as aluminium?
Yes. Our SS 304 friction stays suit outward-opening casement, awning and top-hung sashes in both uPVC and aluminium. Send us the profile you fabricate and we will confirm the fit.
Technical
What track sizes do your sliding rollers fit?
Sliding rollers and bearing carriages are supplied in 15x18 mm, 15x20 mm and 15x24 mm body widths for 15 mm track sections.
What lengths are friction stays available in?
The standard friction stay and the friction arm are available in 10, 12, 14 and 16 inch. The R 50 series friction stay is available in 12, 14 and 16 inch.
Can sashes be levelled after installation?
Yes, on the adjustable products. The two wheel bearing, two wheel roller and four wheel bearing are all height adjustable, so a glazed sash can be levelled on site without lifting the panel out.
Do I need a stainless steel rail with your rollers?
It is worth specifying. Running wheels directly on an aluminium sill lets the running surface groove under repeated sash load, which is what makes a slider feel heavy after a few years. Our 13 mm SS rail gives the wheels a stainless running surface instead.
Business
Do you have minimum order quantities?
Yes, and they differ by product. They range from 100 pairs on friction stays and 100 sets on handle sets up to 5000 metres on locking strip. The MOQ is listed in the specification table on every product page.
Do you work with dealers and distributors?
Send us an enquiry with your business details, the ranges you are interested in and the volumes you expect, and our team will get back to you on terms.
How do I get pricing?
