Designed & made in Perth, WA
Angled inserts that slide into the bottom of your Colorbond-style boundary fence and cover the ledge on the bottom rail. Nothing left for little feet to climb. Fitted in minutes with silicone or a couple of screws.

The problem
Steel boundary fences have a bottom rail with a lip that a child can stand on. Inspectors call it a toe hold, and it can fail a pool barrier check. These inserts sit in each pan of the sheet and cover that ledge, helping keep the non-climbable zone clear.
Push the tongue down behind the lip of the bottom rail. The top cap sits over the rail lip.
A bead of outdoor silicone or a couple of small Colorbond-coloured screws holds it for good.
Fit one insert in every pan (the flat bit between ribs) along the stretch that needs covering.

Which one, and how many?
Measure across your fence sheet from the centre of one rib to the next to pick your profile. Then measure the stretch of fence that needs covering.
| Measurement | Trimclad | Harmony / Metline |
|---|---|---|
| Rib spacing | ~190 mm | ~193–194 mm |
| Pan / trough opening | ~130 mm | ~119 mm |
| Flat rib width | ~60 mm | ~75 mm |
| Tell-tale sign | Wide flat pans | Small V ridge in each trough |
Still not sure? Email me a photo with a tape measure across the sheet and I’ll tell you which fits.

Why I made these
My Colorbond boundary fence had the toe hold. Rather than rebuild the fence, I designed an insert to cover it, and it resolved the issue with my local WA council. I’ve since refined the design with feedback from pool owners, and I print every one myself in Perth.

Questions
It covers the toe-hold ledge on the bottom rail. Your inspector checks the whole barrier, so other footholds like gaps, garden beds and taps still need sorting. Requirements vary by state and council – if in doubt, check with your inspector first.
Pool barrier rules (AS 1926.1) apply Australia-wide, but each council does its own inspections. It resolved the issue for mine in WA.
They come in black or white. For a perfect match, hit them with plastic primer and a can of spray paint from the big green shed.
