Wind-Lock 4x4 Vinyl Fence Post Cap
A flat replacement cap for 4 in (101.6 mm) vinyl/PVC fence posts, for when the original has gone brittle or blown off and the post size or colour is no longer sold. Eight angled flex fins in a 104 mm skirt grip posts from about 100 to 103.5 mm. A slotted 4.5 mm hole in each side lets you fix it with #8 (4.2 mm) screws so it stays on in wind. The cap is 116 mm square with a 3 mm drip lip.
Flex-Fin Chain-Link Post Cap 57-63 mm
This rain cap replaces a missing or rusted cap on a 2-3/8 in (60.3 mm OD) chain-link terminal post or a 60 mm metric round post. Eight angled flex fins grip any post from 57 to 63 mm OD, so an odd-size or out-of-round tube still gets a snug cap. The cap is 76 mm across with a drip lip and a 32 mm skirt. A 4.5 mm side hole takes a #8 self-drilling screw to lock the cap in place against wind and theft.
