Description
A heavy top rotating hinge on an L-shaped bracket that you can weld on or bolt on, for swing gates that turn on a bottom bearing. The zinc-plated bracket fixes to the top of the gate post through three 11mm holes or by welding, and its arm carries a 60mm housing with a sealed ball bearing and a 30mm pin that welds to the top of the gate stile. The housing bolts through a slot in the arm, so it can be moved into line before you lock it. A gate uses one top hinge and one bottom hinge, and the matching 60mm bottom rotating gate hinge, weld or bolt on is the partner for this part. The price shown is for one top hinge, with a minimum order of 4.
What you get
| Bracket | One L-shaped bracket, 10mm thick, with a ribbed arm, a 30 x 15mm slot and three 11mm fixing holes |
|---|---|
| Housing | One 60mm housing, 20mm high, with a sealed ball bearing |
| Pin | One weld-on pin, 30mm across and 10mm high |
| Fixing kit | Bolt, ribbed washer and spring washer on the arm, plus a grub screw in the end of the arm |
| Not included | Post fixings, the bottom hinge, and weld |
Why choose this hinge
Weld it or bolt it. Weld the bracket to a steel post, or bolt it through the three 11mm holes with M10 fixings to steel or masonry. On a stone or brick pier, or a post you do not want to scorch, bolting on is the simple answer.
Sealed bearing. The gate turns on a sealed ball bearing, so it moves smoothly and the bearing is protected from rain and grit.
Set the gate upright. The 30mm slot lets the housing move along the arm, so you can bring the gate truly plumb over the bottom hinge and then lock it. The ribbed arm and washer grip each other, which helps the setting stay put.
Works with a bottom hinge. The bottom hinge carries the weight and this top hinge holds the gate upright, so a pair shares the job properly.
How much will it carry?
| Gate width | Maximum gate weight |
|---|---|
| 1m | 700kg |
| 2m | 350kg |
| 3m | 175kg |
Wider gates put more leverage on the top hinge, so the safe weight falls as the gate gets wider. Always check the weight of the finished gate, including any cladding or infill, and use the figure for your gate width.
Where it is used
Heavy steel driveway and estate gates on stone or brick piers, solid-panel and clad gates, commercial and yard gates, and any gate on a bottom pivot where the top fixing has to bolt on rather than weld.

Fitting
Fit the bottom hinge first and stand the gate on it, propped upright. The top bracket goes on with the bolt on top and the upright plate pointing down the post, so the housing and pin sit underneath the arm. Fix the bracket to the post through the three holes or by welding, with the arm level. Bolt the housing loosely to the arm, set the pin on top of the gate stile, then slide the housing along the slot until the gate is plumb over the bottom hinge. Tack the pin to the stile, check the swing, then tighten the bolt, nip up the grub screw and weld the pin out. Keep the heat short so the bearing is not damaged, and paint the welds with zinc-rich primer.
Care
The bearing is sealed and needs no grease. Check that the bolt on the arm is tight and the welds are sound each spring, and touch up any scratches in the zinc.
Frequently asked questions
Do I need a bottom hinge as well?
Yes. A gate uses one top hinge and one bottom hinge: the bottom hinge carries the weight and this one holds the gate upright. The matching 60mm bottom rotating gate hinge, weld or bolt on uses the same bracket and has the same rating.
Is the price for one?
Yes, the price is for one top hinge, with a minimum order of 4. Each gate leaf takes one of these and one bottom hinge.
Which way up does it go?
With the bolt on top of the arm and the housing underneath. In some product photos it is shown the other way up so you can see the bearing.
What fixings do I need to bolt it on?
Three M10 bolts or resin anchors suited to your post. They are not included.
Is it left or right handed?
Neither. It works on either hand of gate.
