Best Plastic Post Caps

TonGass (24-Pack) True I.D. 6x6' Fence Post Caps - Made from Black Durable Plastic - Protect Wooden Fence Poles Outdoor in Low Profile

  • With inside dimensions of 6" by 6" and an edge height of 1/2", these black plastic fence post caps will fit perfectly on most fence posts.
  • Made from thick, highly durable and weatherproof plastic, our plastic post caps are UV and heat-resistant, impact-resistant and waterproof. There won't be fading, cracking for years to come.
  • The black caps will slip easily on top of the posts. Even when the post is a few millimeters bigger, the caps will flex enough to fit, but it won't stretch further.
  • There are 4 options in securing the caps to the posts: tape, nails, screws and adhesive. For tape, stick some mounting tape inside the cap and then snap on. For both nails & screws, you'll need to drill a pilot hole in at least two sides of the caps. If using an adhesive, ensure that said adhesive will bond on both plastic and wood.
