Buying Guide: Key Considerations for Bi-Fold Door Aligners
What door type and size do you have? Confirm the door thickness and panel dimensions to ensure a proper fit. Look for spring-loaded, self-centering designs for smoother operation and fewer adjustments. Consider material: stainless steel and zinc-plated steel resist corrosion and wear, while carbon steel options can offer higher strength for heavy-use doors.
How many doors need alignment? If you manage several doors, a larger pack (6–8 pieces) can simplify replacement and consistency. For a single door, a 2-pack or 4-pack may be sufficient. Check installation requirements—some aligners mount to the back of doors, others fit into jambs or floor stands.
Is aesthetics important? If you have exposed hardware, choose finishes like brass, silver, or galvanized steel to match existing fixtures. Ensure the finish resists rust and tarnish in your climate. Finally, verify that the kit includes all mounting hardware or if you must source screws and brackets separately.
