Q&A
Why does this part have several numbers?
LiftMaster and Chamberlain rail hardware is often listed under current, older, and shortened part numbers such as 12D598-1 and 041D0598-1.
Is this bracket only for square rail assemblies?
This listing is written for select square rail assemblies, so the rail style should be checked before ordering.
Can I use this as a door bracket?
No. This is rail hardware and should not be substituted for a garage door bracket or opener arm bracket.
Should I replace the rail too?
Only if the rail is bent, cracked, or damaged. A bracket replacement will not correct a damaged rail assembly.
How do I avoid ordering the wrong bracket?
Match the original part number, bracket shape, hole pattern, and the opener parts diagram before purchase.
