Fence Couplers, Clamps and Fixings

Couplers, Clamps & Fixings: what to know before you buy

Standard and Lockable Couplers

The standard fence coupler is two galvanised steel pieces that clamp around the outer bars of adjoining temporary fencing panels and tighten with a 7/16 inch scaffold spanner. Use two per panel joint, one at the top and one at the bottom. The lockable fence coupler encloses its nut in a protective housing, so it can only be tightened or loosened with the anti-tamper spanner. That deters people from taking the fence line apart.

Stopping Panels Being Lifted

An anti-lift hook fits beneath a temporary fence foot and hooks onto the coupler, so the panel cannot simply be lifted out of its feet. It is galvanised steel, weighs 0.5kg and can be used with lockable couplers for added protection. Pair it with the anti-tamper double-ended spanner, which combines a 7/16 inch / 21mm socket with a security prong socket.

Ground Fixing and Post Concrete

The Fence-Lok V-Mesh system locks V-mesh fencing to the ground with a foot bracket, stabilising brace and post U-bracket, leaving no trip hazard on the public side. Choose flanged ground screws for soil or grass, or M12 screws and anchors for concrete and asphalt. It is listed as suitable for tree protection and root protection zones; see the full Fence-Lok range. For fixed posts, PostFix concrete comes in 20kg bags on a pallet of 60. One bag fills a post hole of about 250 x 250 x 350mm and sets in around 5 to 10 minutes.

Spares for Water-Filled Barriers

For RB22, GB2 and Defender 50 runs, the fixing bolt set gives four complete fixings, each an M12 nut, an M12 x 30mm bolt and two washers. The connection post, powder coated white, gives a mesh or panel fixing point at two heights and comes with four sets of fixings. See our Chapter 8 and water-filled barriers.

01How many couplers do I need per panel joint?

Use two standard couplers per joint, one at the top and one at the bottom. They tighten with a 7/16 inch scaffold spanner or our standard coupler spanner.

02What is a lockable fence coupler?

An anti-tamper coupler with its nut enclosed in a protective housing. It can only be adjusted with the anti-tamper coupler spanner, which deters people from taking the fence apart.

03Which spanner fits lockable couplers?

The anti-tamper double-ended spanner. It combines a 7/16 inch / 21mm socket with a security prong socket.

04Are fence couplers load bearing?

No. The standard fence coupler joins adjacent panels and is not designed for load-bearing use.

05How does the anti-lift hook fit?

The lower part sits beneath a temporary fence foot and the upper part hooks onto the coupler. Use it with lockable couplers for added protection against panels being lifted out.

06Which fixings come with the Fence-Lok V-Mesh system?

Choose soil/grass, concrete or asphalt on the product page. Our catalogue lists flanged ground screws for soil, M12 concrete screws for concrete and M12 asphalt anchors for asphalt.

07What bolts fit RB22, GB2 and Defender 50 barriers?

The fixing bolt set holds four M12 nuts, four M12 x 30mm bolts and eight M12 washers. It fits all three barrier systems, so one spare covers a mixed fleet.

08How quickly can you deliver?

Stocked items ordered online before 2pm are dispatched within 1 to 2 working days, and made-to-order items take 1 to 3 working days. Delivery is free on orders over £1,500 exc. VAT in England and Wales.
