Know before you buy
A little detail.
A much better fit.
Practical answers for finding a replacement with confidence.
Will any bifold roller fit my door?
No. Rollers and guides differ between door systems. Match the manufacturer, part number, dimensions and fixing positions. Appearance alone does not confirm compatibility.
What measurements should I check?
Compare the component’s overall size, wheel diameter, shaft size and fixing centres where relevant. Check the product details for the dimensions specific to that part.
How do I tell left and right parts apart?
Handing depends on the component and the manufacturer’s viewing convention. Compare the product photographs and stated handing carefully before ordering.
Should I remove a component to identify it?
Start with photographs and visible markings. Some parts support the weight of the door. If removal affects the panel support or locking system, ask a competent installer to identify it safely.
