LiftMaster K75-34824 Chain Guard Kit — SL575 / Documented SL585 Applications
LiftMaster K75-34824 Chain Guard Kit — SL575 / Documented SL585 Applications
The LiftMaster K75-34824 is the chain-guard service kit identified in SL575 manufacturer parts information and offered for SL575 / SL585 gate-operator applications. The documented kit brings together the guard, chain guides and retainers used around the specified chain path. It restores the intended mechanical guarding arrangement rather than replacing the drive chain or sprocket. Match the exact operator revision and mounting layout, and inspect the surrounding drive for damage before treating a missing or broken guard as an isolated cosmetic repair.
Compatibility — Models, Versions and Exclusions
| Model or selection point | Compatibility requirement |
|---|---|
| SL575 | Manufacturer service documentation identifies this chain-guard kit. |
| SL585 | Supplier-listed application; confirm the model-specific kit and mounting arrangement. |
| Later U / UL variants | Check their own parts drawings rather than extending legacy fit automatically. |
| MAXUM CHNGUARD | Different commercial-door accessory; not an interchangeable SL575 guard. |
| Damaged chassis or chain path | Requires separate inspection and correction before the guard is fitted. |
Restore the Guard Without Masking a Drive Problem
A chain guard can be damaged by impact, loose hardware or interference with a misaligned drive. Inspect the chain path, guide locations and mounting supports before ordering. If a moving chain has contacted the guard abnormally, identify the cause; fitting a new cover without correcting alignment or wear can repeat the failure.
The chain guides and retainers are part of the documented assembly, so verify the full kit inventory rather than comparing only the outer cover. Position the components according to the operator instructions and maintain the required clearances. A guard must not be trimmed or forced into place to compensate for a different model, bent support or incorrectly routed chain.

Before Ordering
- Record the exact operator model and locate K75-34824 in its service information.
- Inspect the guard mounts, guide positions and chain alignment.
- Check the chain and sprockets for damage or abnormal contact.
- Confirm the current kit includes the required guard, guides and retainers.
Package Contents and Separate Requirements
The manufacturer identifies a kit consisting of the chain guard, chain guides and retainers. Confirm the current supplier package and any fasteners needed for installation. The drive chain, master links, sprockets, shaft and complete operator are separate items unless expressly bundled. A kit can restore the intended guarding only when its mounting structure and surrounding drive components remain serviceable.
Safety Warnings — Read Before Installation or Service
- WARNING: Exposed chain and sprocket drives can trap fingers or entangle clothing and cause serious injury. Keep people clear and use a qualified gate technician.
- Isolate all applicable power and secure the gate before removing guards or reaching near the chain path.
- Do not operate the gate with missing guards or bypass protection to test a damaged drive. Follow the manufacturer’s controlled service procedure.
- Restore the complete guarding arrangement and verify clearance, travel, reversal and required entrapment protection before normal use.
Related Products and Important Differences
- MAXUM CHNGUARD chain guard — a different commercial-door accessory, shown for identification only; not an SL575 substitute.
- LMRRUL monitored photo eye — a separate protection option only where the exact operator and controller approve it; not a replacement for mechanical guarding.
Frequently Asked Questions
Does this kit include a replacement drive chain?
No chain is promised. The documented kit consists of the guard, guides and retainers.
Is it the same as the MAXUM chain guard?
No. MAXUM CHNGUARD belongs to a different commercial-door platform and must be selected separately.
Can a new guard fix a misaligned chain?
No. Alignment and worn or damaged drive components require their own correction.
Does the guard replace gate safety sensors?
No. Mechanical guarding and the operator’s required entrapment-protection devices serve different purposes; both must be maintained.
