LiftMaster POWERHINGE Heavy-Duty Steel Gate Hinges — Pair, Up to 3,000 lb

The LiftMaster POWERHINGE is an all-steel, weld-on hinge pair for a properly designed steel swing gate and steel support post. LiftMaster lists a capacity of up to 3,000 pounds per pair, making this the heavy-duty steel option in the POWERHINGE family. Choose it by the gate structure, mounting surfaces and hinge alignment—not by weight alone. The pair provides the gate’s pivoting support; it does not include an operator, repair a weak post or replace the safety devices required for an automated gate.

Compatibility — Models, Versions and Exclusions

A Strong Hinge Pair Needs a Sound Gate Structure

The 3,000-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.

Specifications and Product Identification

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 POWERHINGE 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 3,000-pound rating for each hinge?

No. LiftMaster publishes the capacity per pair. The supporting structure and installation still need to be suitable for the actual gate.

Is this the aluminum POWERHINGE version?

No. This listing is the all-steel POWERHINGE. The POWERHINGE² and POWERHINGE³ variants have different material combinations and published ratings.

Will these hinges fix a sagging gate?

Only if the repair addresses the actual cause. A damaged frame, failing post or incorrect mounting needs correction as part of the job.

Do these hinges make a gate ready for automation?

Not by themselves. The gate must move correctly, and the operator, mounting geometry and safety devices must be selected for the complete installation.
