The Simpson PBV10PC PBV 10-in. Black Powder-Coated Hidden Standoff Post Base is part of the Simpson Strong-Tie Decorative Hardware line, a collection of pre-finished connectors engineered for exposed wood applications where structural integrity and visual appeal must work together. Designed specifically for viga-style round posts, this circular standoff base creates a clean, concealed connection between the post and concrete - delivering verified load-rated performance without the uncertainty of custom-fabricated alternatives. Attachment is made to concrete using a threaded rod and epoxy, while Strong-Drive SDS Heavy-Duty Connector screws secure the base to the bottom of the viga post for a hidden, finished look that holds.

Key Features

• Round shape to match viga-style posts - the circular profile follows the natural form of viga-style round posts, creating a visually cohesive and seamless connection at the base.
• 1-in. standoff height - elevates the post end off the concrete surface so moisture can escape, helping prevent rot and extending the life of the post.
• 14-gauge steel construction - provides the structural strength needed for load-rated performance in exposed architectural and outdoor applications.
• 10-in. diameter sizing - purpose-built to fit 10-in. viga-style round posts precisely, eliminating guesswork and ensuring a properly engineered fit.
• Black powder-coat finish - delivers a refined, decorative appearance that complements exposed wood framing while providing a durable pre-finished surface ready for installation.

Why This Product

• Pre-engineered and load-rated for confidence - unlike custom-designed or shop-fabricated connectors, this post base is pre-engineered and tested to verified design loads, giving builders and designers a dependable, code-ready solution for structural post connections.
• Hidden connection for a cleaner finished look - the concealed attachment method keeps hardware out of sight, making this base a strong fit for exposed architectural applications, covered patios, and decorative timber structures where appearance matters as much as performance.
• Built-in rot protection through standoff design - the 1-in. standoff is not an afterthought but a core design feature, lifting the post end clear of the concrete so water drains away rather than pooling against the wood grain.
• A purpose-built fit for viga-style round posts - the round form and 10-in. diameter are specifically matched to the profile of viga posts, making this a direct solution for Southwestern, Mediterranean, and rustic timber architectural styles that use round structural posts.

Frequently Asked Questions

What type of posts is the PBV10PC designed to work with?

The PBV10PC is specifically designed for viga-style posts. Its round, 10-in. diameter shape is engineered to match the profile of viga-style round posts, creating a clean and visually cohesive hidden connection.

How does the PBV10PC attach to the concrete and the post?

This hidden standoff post base attaches to concrete using a threaded rod and epoxy. It connects to the bottom of the viga post using Strong-Drive SDS Heavy-Duty Connector screws - specifically (4) 1/4 in. x 3 in. SDS screws and (1) 5/8 in. diameter anchor bolt - for a secure, concealed connection.

Why does the PBV10PC include a 1-in. standoff?

The 1-in. standoff is designed to help prevent rot at the end of the post by elevating the post base off the concrete surface. This gap allows moisture to drain away and air to circulate, helping to extend the life of the post.

Is the PBV10PC a load-rated connector?

Yes. As part of the Simpson Strong-Tie Decorative Hardware line, the PBV10PC is pre-engineered and tested. It is a load-rated product verified to perform to design loads, unlike custom designed and fabricated connectors.
