Technician Note
This assembly is tied to both opener model and door height. If the chain is the wrong length, the opener may not travel correctly or may not tension properly.
Before Ordering
- Confirm model PD752 or PD752D, or verify the same part number in the diagram
- Confirm the door height is 7 feet
- Confirm the opener is chain drive
- Inspect the trolley and sprocket for wear
- Do not order for belt drive or screw drive systems
Professional Advisory
After replacing chain and cable hardware, opener force and travel should be checked according to the opener manual. Do not increase force settings to overcome a binding door or damaged rail.
Product Questions and Answers
Is 41A5807-3 for a 7 foot door?
Yes. This chain and cable kit is used for select 7 foot door chain drive opener applications, including PD752 and PD752D references.
Can I use this chain and cable kit on an 8 foot door?
No. Door height changes the chain and cable length. An 8 foot door normally requires a different chain assembly.
Does this kit fit PD752D?
PD752D is one of the common model references for this part. Still match the opener parts diagram before ordering.
Is this a belt replacement?
No. This is a chain and cable assembly for chain drive openers. Belt drive openers use belt kits.
Why does the chain length matter?
The correct chain length allows the trolley to move through the intended travel range and lets the chain tension properly on the rail.
