Adjustable Wrap-Around Gate Hinge for 30mm Box Section, M16, 50mm Round Plate

An adjustable gate hinge that wraps round the gate frame itself. A folded steel strap goes round a 30mm square box section upright, and a forked head on an M16 threaded stem carries it back to a 50mm round jointing plate, which seats against a steel post. Wind the stem in or out to set the gap between gate and post, then lock it off, so the leaf can be corrected after it is hung rather than cut or packed on site. The strap takes the box section directly, without a separate hinge pin. The price shown is for one hinge, with a minimum order of 6, because a leaf normally takes two.

Why this hinge works

You can adjust it after the gate is hung. The M16 stem gives you in and out movement at the post, so the closing edge can be brought true without taking the leaf off or packing behind the plate.

The strap grips round the upright. The folded band goes round all four faces of the box section rather than a single weld on one face.

The hinge turns on two bolts, top and bottom. The forked head pivots on a pair of hex bolts in line with one another, so the part that wears is a bolt rather than the gate or the post.

The round plate stays small on the post. At 50mm across it suits a narrow steel post where a four-hole plate would not fit, and it can be welded on or used with the stem passed through the post.

Where it is used

Light gates on 30mm box section where the post is a steel section you can drill or weld: side gates to yards, plant room cages and the smaller gates in a run of steel fencing. Fit a pair to each leaf, one near the top and one near the bottom.

Specifications

Choosing the right hinge

Measure your gate upright across both faces and match it to the strap. This one takes 30mm square section with 30 x 30mm clear inside. Choose this rather than the 80mm square plate when your post is steel and there is no room for a four-hole plate. The 50mm round plate is smaller and fixes differently: welded to the post, or with the stem passed through it.

Fitting and care

On a steel post, weld the round plate flat to the post face after grinding off the zinc at the joint. Or drill through the post, pass the stem through and tighten up against the plate with the nut on the far face. Post fixings are not included.

The strap carries a small hole in its outer face. Fix the strap to the upright by welding or with a fixing through that hole; its size is not published. If you weld, grind off the plating first and repair it afterwards with zinc-rich paint. Stand the gate on packers, set the gap with the stem and lock everything tight.

Check the pivot bolts, stem nuts and fixings at each routine inspection and grease the pivots. Zinc plating is a light finish, so touch up scratches on an outdoor gate.
