What type of gate is this hinge designed for?

It is designed for very large, fully framed swing gates with a structural frame capable of accepting the bolt-on plate.

Can I use it on a gate without a full frame?

No. The 8″ mounting plate must be through-bolted to a suitable structural gate frame.

Can it be used on single and double swing gates?

Yes. Use it on properly designed single gates or on each leaf of a properly designed double swing gate.

Can it be used on a motorized gate?

Yes, when the gate, post, hinge quantity and spacing, operator geometry, welds, and safety system are properly designed for the powered installation.

Is it compatible with the Alumission 3″ × 3″ × 8′ steel post?

Yes. The post-side hinge tab can be welded to Alumission’s heavy-duty steel gate post when that post is suitable for the completed gate design.

What size is the bolt-on plate?

The custom gate-side plate measures 8″ long by 2″ wide.

How many mounting holes are in the plate?

The plate has two holes, each 3/8″ in diameter.

What size is the barrel hinge?

The barrel hinge body is approximately 5″ long and 1″ in diameter.

Does the hinge contain a bearing?

Yes. It uses a single steel ball bearing inside the barrel assembly.

Can the hinge be lubricated?

Yes. A grease fitting provides access for periodic lubrication.

How does the hinge attach to the gate?

The 8″ × 2″ plate is through-bolted to the fully framed gate using appropriately selected bolts, nuts, and washers.

How does it attach to the post?

The opposite steel tab is welded to a structural steel gate post by a qualified welder.

Are bolts and nuts included?

No. Mounting hardware must be selected for the gate frame and installation conditions.

How many hinges do I need?

The required quantity depends on gate size, weight, frame stiffness, hinge spacing, wind exposure, operator forces, post strength, and installation design. Consult a qualified gate professional or engineer.

What is the hinge weight capacity?

No universal finished-gate capacity is stated. Capacity depends on the complete gate, number and spacing of hinges, welds, post, frame, site conditions, installation, and maintenance.

Is the price for one hinge or a pair?

The listed price is for one hinge. Select the quantity required for your gate design.

What maintenance is required?

Periodically inspect fasteners, welds, corrosion protection, alignment, and gate movement, and lubricate the bearing through the grease fitting as required.
