LiftMaster POWERHINGE3 Aluminum Swing-Gate Hinges — Pair, 1,000 lb
LiftMaster POWERHINGE3 Aluminum Swing-Gate Hinges — Pair, 1,000 lb
The LiftMaster POWERHINGE3 is the aluminum version of the POWERHINGE machined-block swing-gate hinge family, supplied as two hinges and rated by LiftMaster for up to 1,000 pounds per pair. It provides a material-specific choice for an appropriately designed aluminum mounting arrangement, distinct from the mixed steel/aluminum POWERHINGE2 and all-steel POWERHINGE versions. Selection still depends on gate width, mounting geometry, frame condition and post support. A hinge pair provides pivoting support; it does not include automation equipment or correct an undersized foundation or damaged gate structure.
Compatibility — Models, Versions and Exclusions
| Model or selection point | Compatibility requirement |
|---|---|
| Appropriate aluminum gate and support arrangement | Have a qualified fabricator confirm materials, attachment method and structural suitability. |
| POWERHINGE2 | Mixed steel / aluminum version; separate material configuration. |
| All-steel POWERHINGE | Different published capacity; do not transfer its rating to POWERHINGE3. |
| Existing gate repair | Check hinge position, frame, post and mounting surfaces before replacement. |
| Automated swing gate | Mechanical hinge fit does not establish operator or safety-device compatibility. |
A Strong Hinge Pair Needs a Sound Gate Structure
The 1,000-pound figure is the published capacity of the pair, not a rating for each individual hinge or a guarantee for the entire gate installation. Gate width, frame condition, post support and the mounting arrangement still affect selection. A qualified installer should evaluate the complete structure before treating a hinge upgrade as the solution to a sagging or difficult-to-move gate.
Correct alignment matters as much as the hardware choice. LiftMaster’s installation instructions require the hinge shafts to share proper alignment and warn that incorrect positioning can cause poor operation and shaft failure. The gate should move correctly through its intended travel before an operator is connected or returned to service. Increasing operator force is not a repair for a binding hinge or distorted frame.

Before Ordering
- Confirm the gate’s weight, width, construction and intended swing path.
- Have the post, foundation, frame and existing weld areas inspected.
- Compare the mounting geometry with the current POWERHINGE installation drawing.
- Plan how the gate will be supported safely while old hinges are removed and new ones fitted.
Package Contents and Separate Requirements
The listing is for one pair of POWERHINGE3 hinges. A gate frame, post, operator, latch, welding materials and site support equipment are separate requirements. Do not assume this is a bolt-on conversion kit for an existing hinge arrangement. Before ordering for a repair, confirm whether the original mounting areas can accept this weld-on design or need professional structural work.
Safety Warnings — Read Before Installation or Service
- WARNING: A falling or unexpectedly moving gate can cause serious injury or death. Have a qualified gate professional support and secure the gate before any hinge is removed.
- Isolate an automated gate’s power and prevent movement throughout the repair. Never rely on the operator arm alone to support the gate.
- Welding and structural installation require appropriate training and protection. Follow the manufacturer’s mounting instructions and keep hinge shafts correctly aligned.
- Keep people clear during testing. Restore and test all required gate protection before returning an automated installation to normal use.
Related Products and Important Differences
- LMRRUL monitored photo eye — a separate non-contact protection option where approved by the installed gate operator; it does not support the gate.
- LMWEKITU monitored wireless edge kit — a connection system for compatible safety edges and controls; select it independently of the hinge pair.
Frequently Asked Questions
Is the 1,000-pound rating per hinge?
No. It is the published capacity of the pair in a suitable installation.
How does it differ from POWERHINGE2?
POWERHINGE3 is the aluminum version; POWERHINGE2 uses a mixed steel/aluminum construction.
Can it fix a leaning post?
No. Post, foundation and frame defects require separate structural repair.
Does aluminum construction make alignment less important?
No. Correct hinge alignment and sound mounting remain essential to safe gate movement.
