Using clear western red cedar, Nantucket Post cap manufactures some of the finest post caps and finials available in the industry. Cedar has a very long standing, strong resistance to mold and mildew. Its low density makes it less likely to swell, warp, cup or twist, compared to other soft and hardwoods. Due to the caps being installed horizontally on top of the posts, they receive the most sun exposure. So even though you may leave a cedar fence to weather naturally, we highly recommend treating not only the cedar caps but all wood species caps. Our stock Island Cedar Caps are sized to fit standard nominal wood posts 4 x 4. Inside width 3½ in. x 3½ in.
Cedar has a great resistance to moisture, decay and insect damage
Nantucket Post Cap recommends sealing cedar caps before installation
Use an exterior urethane, stain or paint to ensure long life
Slip-over fence caps are crafted using a 5 piece construction with V-nails in each corner of the molding. Twelve or more stainless steel staples are used to permanently fasten the molding to the underside of the wooden post cap.
For a nail-free look, simply apply an exterior marine adhesive like 3M 5200 to the top of the post and slip the post cap over. Stainless steel nails may be used as an alternative, but not necessary. Pre-drilling is recommended.
