Key item features

  • Durable Construction: These pyramid fence post caps are made from heavy-duty, durable plastic with UV inhibitors, designed to protect treated posts from water and sun damage, ensuring longevity.

  • Versatile Finish: Available in black or white, these caps feature a smooth, seamless finish and can be painted with a suitable plastic-adhering paint for customized aesthetics.
  • Compact Dimensions: Each cap measures approximately 4.125 x 4.125 inches outside, with an overall height of 1.75 inches and an inside cap edge height of 1 inch.
  • Multi-Pack Option: This product is offered as a 15-pack, with other pack sizes available, providing options for various project scales.

good

for the price they are ok. a little larger than a fence post, if it has a top on it., it is ok, but will still need to be sanded down. i may still spray paint with granite spray. to give a more expensive appeal.

post caps

overall good for the price, but be aware they are TRUE 4x4 ....meaning the majority of "4x4" posts are actually smaller than that so we had to use a screw on top to keep it on but not a big deal
