Post and Column Bases secure the bottom of posts or columns to concrete and are perfect for decks or patio covers. Models are available for attaching to existing hardened concrete, wet concrete, as well as wood. The BC series offers dual purpose post cap/base for light cap or base applications.

  • Provides a positive connection for a post to a wood deck
  • Stronger than angled nailing or screw fastening
  • Reduces the chance of the post splitting and eliminates nailing into end grain
  • Not recommended for non top-supported installations (such as fences or unbraced carports)
  • Made from 18-Gauge steel
  • Z-MAX galvanization offers extra corrosion resistance for exterior and treated-wood applications
  • Install with 16d common nails or #10 x 1-1/2 in. Strong-Drive SD screws

Rated 5.0 out of 5.0 by great product Love it. It worked great for joining 2 4 x 4 posts together. January 21, 2014
Rated 5.0 out of 5.0 by Footing Post to Support Beam - no problem I got these post caps to add some additional support posts to my old decks. They work great, are easy to install and are far superior to the old method of nailing short lengths of 2x4 on the posts. I highly recommend them. November 19, 2013
Rated 5.0 out of 5.0 by good stuff ! These clips are awesome , they fit perfect to the job for which they are made and are easy to install ! :0 June 17, 2014
Rated 3.0 out of 5.0 by Average Product at an average price This was just like any Simpson Strong Tie I'd buy anywhere else. I am just continually disappointed with the lack of coupons that save me more than 10%. I am always looking for great deals and almost never get them at HD. I'm not trying to be mean but a 10% coupon pretty much saves me the tax on the purchase. Please give me more of a reason to shop HD! January 14, 2014
