Adjustable Wrap-Around Gate Hinge for 50 x 30mm Box Section, M16, 80 x 80mm Square Plate

An adjustable gate hinge that wraps round the gate frame itself. A folded steel strap goes round a 50 x 30mm rectangular box section upright, and a forked head on an M16 threaded stem carries it back to an 80 x 80mm square plate with four holes, which fixes to the 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 square plate suits posts you cannot weld to. It fixes through four 10mm holes at 55mm centres, so it works on masonry, concrete and timber as well as steel.

Where it is used

Gates framed in 50 x 30mm rectangular box section, which gives a slim gate a stiffer leaf: access gates to service yards, enclosure gates on factory sites and bin store doors in a steel surround. 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 50 x 30mm rectangular section with 50 x 30mm clear inside. The strap is longer than the square 30mm version: it runs the long 50mm side of the box section out from the hinge head, with 30mm clear across. The plate and the M16 stem are the same size as the 30mm square version.

Fitting and care

Mark the four plate holes on the post, using 10mm bolts or anchors to suit, and fix the plate in the position you want the hinge. Fixings for the post 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.
