A top hinge that drops into the end of a 50mm box section gate upright. A tapered plug pushes into the open top of the upright and carries a turning head, and a folded steel bracket with four 9mm holes fixes that head to the post. Nothing is welded to the frame, and from the front you see only the head and the bracket. A gate leaf also needs a bottom hinge to work with this one. That matching lower hinge is sold separately, so if you cannot see it on our site please call us. The price shown is for one upper insert hinge, with a minimum order of 5, because hinge sets are usually bought for more than one leaf.

Why this hinge works

It fits into the frame, not onto it. The plug disappears into the end of the box section, so the upright stays plain and square at the top.

A bearing at the turning point. The plug is hollow and carries a ball bearing, so the head turns on a bearing rather than on a plain pin.

Adjustment at the head. A toothed slide plate and a small screw at the end of the top leg of the bracket let you trim the position of the gate. The range of adjustment is not published for this line.

A simple post fixing. The upright leg of the bracket has four 9mm holes, set out in two rows, and fixes to the face of the post with screws or bolts to suit.

Where it is used

Neat pedestrian gates and small access gates built from 50mm box section, such as entrance gates at commercial buildings, plant areas and enclosures. It suits work where the top of the gate should look tidy. It is only for box section with an open top end, not for round tube.

Choosing the right hinge

Measure the inside of your box section before ordering. The tip of the plug is 43mm across, so a 50mm section with a heavy wall may be too tight, and the plug needs to go in squarely. The 49mm flange then sits on the end of the tube. If you would rather not fit into the frame, the upper hinge and bottom hinge sets below carry the upright in a saddle instead, and suit more section sizes.

Fitting and care

Clean and deburr the open end of the box section, and check the inside is free of weld spatter. Push the plug in squarely until the flange meets the end of the tube. Fix the bracket to the post with suitable bolts or screws through the four 9mm holes; those fixings are not included. Fit your bottom hinge, hang the gate and use the toothed plate and small screw to bring it into line before the final tighten.

Check the fixings at each routine inspection and keep the bearing area free of grit. Touch up scratched plating with a zinc-rich paint, especially outdoors.

Frequently asked questions

Is the price for one hinge?

Yes, the price is for one upper insert hinge, and the minimum order is 5. Each leaf needs one of these and one matching lower hinge.

Do I need a separate bottom hinge?

Yes. This is the top half of the set. The matching lower hinge is sold separately; call us and we will confirm it and supply it with your order.

Will it fit a heavy wall 50mm section?

It depends on the wall thickness. The plug tip is 43mm across, so measure the inside of your section and call us if you are unsure.

Can I use it on a gate with a welded top cap?

No. The plug needs an open end to go into. It will not work on a capped or closed section.
