Press or tap the cap firmly down over the post top so it sits flush, and secure with a suitable exterior-grade adhesive or a stainless steel nail through the side if required. Store caps flat and off the ground in a dry location until they are needed, keeping them away from prolonged direct contact with wet concrete or soil.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWhich size post cap do I need for a standard fence post?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe 96 x 96 x 23mm cap is designed for 75mm (3 inch) posts, and the 120 x 120 x 26mm cap fits 100mm (4 inch) posts.
