Marthas Vineyard Post Topper by Nantucket Post Caps
Overview
The Martha’s Vineyard Non-Slip Over Post Cap by Nantucket Post Cap adds a clean, finished appearance to wood deck, fence, and porch posts. Unlike a traditional slip-over cap, it sits directly on top of the post and is secured with exterior-grade marine adhesive and stainless-steel finish nails.
Crafted from clear, kiln-dried Western Red Cedar or Redwood, its solid one-piece construction provides natural beauty and dependable outdoor durability. The unfinished wood can be sealed to preserve its natural color or painted or stained to complement your project.
Key features:
- Available in Western Red Cedar
- Solid one-piece wood construction
- Fits numerous square and rectangular post sizes
- Installs directly onto the top of the post
- Can be painted, stained, or clear-coated
- Helps protect exposed post ends from weather
- Ideal for decks, fences, porches, and outdoor structures
Materials & Construction
Clear Cedar
- Made from premium clear Western Red Cedar, both known for outdoor durability and natural resistance to moisture and insects when finished properly.
- Constructed from one‑piece, solid wood — there’s no separate molding trim under the cap, just a clean, single cap that sits on the post.
Sizes & Fit
- Available for a wide range of actual post dimensions from approximately 3‑1/2″ up to 6‑1/2″
- Be sure to measure the actual outside width of your post before ordering — these caps are sized to match real measurements, not “nominal” lumber sizes.
Installation
Simple, Minimal Assembly
- Designed to sit on top of the post — no complex assembly or internal trim pieces to install.
- You can secure the cap with exterior marine adhesive (e.g., 3M 5200) and/or stainless‑steel nails if you want extra holding power.
Finishing Before Installation Is Recommended
-
Because this is unfinished wood, applying a sealant, stain, or paint before installation will dramatically extend its life and help resist cracking, checking, and moisture damage.
