Galvanised twin pin clips for fixing 150x50mm concrete gravel boards to concrete posts. The backplate sits flush against the board face and the two pins locate into the post. No drilling, no bolts. Box of 25.
These galvanised gravel board clips are made for fixing 150x50mm concrete gravel boards to concrete fence posts. The backplate presses flush against the face of the gravel board and the two pins locate directly into the post, holding the board firmly without bolts, screws, or drilling through the post. It is a clean installation method that has been standard in the fencing trade for good reason.
The twin pin design holds the gravel board securely while still allowing removal and replacement if needed later. That matters on any job where ground conditions may shift or boards may need swapping out over time. A customer asking you to come back and dig out a bolted gravel board six months down the line is not a fun afternoon, so the removable nature of this fixing is genuinely useful.
Where These Gravel Board Clips Work Best
These clips are designed for use with concrete gravel boards and concrete posts only. The galvanised finish protects against rust and corrosion at ground level, where the clips will regularly be in contact with damp soil and standing water. A clip that corrodes early loses its grip and lets the board shift, which is not a situation worth risking.
These gravel board clips suit the 150x50mm concrete board profile. They are not suitable for timber boards or timber posts. If your concrete posts have a slotted channel, the boards may sit directly in the slot without needing clips at all. These clips are for posts without a slot, or where a smooth-faced post is being used alongside a slotted board.
Pack Size for Trade Use
A box of 25 covers approximately 12 bays, based on two clips per bay. For a standard single-side garden fence that is usually about right. For larger sites or back-to-back jobs, order a couple of boxes to avoid running short mid-run. The clips arrive ready to fit with no additional treatment needed.
Pro Tip: When fitting these clips, press the backplate firmly against the gravel board before pushing the pins into the post to make sure the board sits level before the pins are fully seated.
Galvanised twin pin gravel board clips are used during the installation of concrete panel fencing, securing the bottom gravel board to concrete fence posts at ground level. They are a standard fixing on residential garden fencing jobs, new-build housing developments, and commercial boundary fencing where concrete posts and concrete gravel boards are specified. Fencing contractors, landscapers, and groundwork teams all use these regularly as part of a straightforward panel fence installation.

How many clips do I need per gravel board?
Two clips per gravel board, one at each post. A box of 25 therefore covers approximately 12 full bays. For a standard single-side garden fence, one box is usually enough. For larger runs, order an extra box to be safe.
Will these clips work with slotted concrete posts?
No. If your concrete posts have a slotted channel, the gravel board sits directly in the slot and clips are not required. These clips are for use with smooth-faced concrete posts where there is no slot for the board to locate into.
These gravel board clips are manufactured from steel with a galvanised coating to provide corrosion resistance in outdoor ground-level conditions. The twin pin design locates into the face of a concrete post, with the backplate spanning the face of a 150x50mm concrete gravel board. The galvanised finish is suitable for permanent outdoor installation without any additional treatment or priming before use.
