Product Description

Ironwood® Post Base Single Rail Saddles by OZCO® OWT — Connect One 2×4 Rail to 4×4 or 6×6 Posts

One Rail, Clean Finish — Integrated post base with a single 2×4 rail saddle for tidy, repeatable top-rail connections
Inline or Corner — Mount the rail straight through or at 90° to create in-line posts or true corners with the same hardware
Field-Friendly Fastening — Hex Cap Nuts drive with a 3/8″ socket; rail screws use a T25 Torx bit for quick installs
Outdoor-Ready — Heavy-gauge, pre-galvanized steel with a black exterior powder coat; approved for ACQ-treated lumber
Ironwood Aesthetic — Decorative hardware and geometry match the Ironwood OWT line for a cohesive look

Build better-looking guard and rail sections with the Ironwood Post Base Single Rail Saddle. Each assembly anchors your 4×4 or 6×6 post and locks a single nominal 2×4 rail at the correct height, helping you hit common residential layouts with less measuring and shimming. The pre-engineered plate stack, included fasteners, and consistent driver sizes streamline production on decks, porches, and decorative rail projects—while the Ironwood style keeps visible hardware looking intentional.

Why Choose This

Speed & consistency — Pre-set geometry reduces layout time and driver swaps
Durability — Galvanized substrate plus powder coat stand up to weather
System look — Coordinates with Ironwood posts, beam brackets, and accents

Installation

Set and plumb the post, then anchor the post base to your surface per plan. Install the single rail saddle (inline or at 90°), seat the 2×4 rail, and drive the included fasteners — use a 3/8″ hex driver for Hex Cap Nuts/Timber Screws and a T25 bit for the #12 rail screws. Always fasten into sound lumber and follow local code for guard height, spacing, and loads.

Buying Guide

Choose your post size: Select the 4×4 or 6×6 version to match your posts.
Coordinate hardware: For additional connections on the same project, pair with Ironwood Post-to-Beam Brackets and keep OWT 1/4″ Timber Screws on hand in common lengths.
Match single vs. twin: Use Ironwood Post Base Twin Rail Saddles where you need to capture two rails on the same post.

Frequently Asked Questions

Can this bracket form both straight runs and corners?: Yes. The single rail saddle supports an in-line rail or a 90° corner on the same post.
What driver bits do I need?: A 3/8″ hex driver for Hex Cap Nuts and OWT Timber Screws, and a T25 Torx bit for the #12 rail screws.
Is it compatible with pressure-treated lumber?: Yes. The pre-galvanized, powder-coated steel is suitable for ACQ-treated materials.
What rail size does it accept?: One nominal 2×4 rail (approximately 1-1/2″ × 3-1/2″) per post base assembly.

Comparison

Ironwood Post Base Single Rail (this item): Anchors post and captures one 2×4 rail for inline or corner layouts.
Ironwood Post Base Twin Rail: Same concept for two 2×4 rails — ideal for mid-span posts.
2×4 Top Rail Saddle: Attaches a single top rail to a post where a base plate isn’t required at that location.
