Product Description
OZ-Post® 238-IS/PB Steel-to-Steel Post Base — Fits 2-3/8″ (2.375″ O.D.) Round Posts
- Surface-Mount Foundation — Secure a 2-3/8″ round steel post to concrete, asphalt, wood, or steel substrates without core drilling
- Compression Collar Grip — Tightens around the pipe for a snug, no-slip fit (ideal for signs, fence terminals, gates, bollards)
- Heavy, Hot-Dip Galvanized Steel — 3 mm (~0.12″) thick base engineered for outdoor service
- Tested Lateral Strength — Rated up to 750 lb lateral load (installation and substrate dependent)
- Reusable Design — Unbolt, relocate, and re-use for temporary or modular projects
When your post needs to land on a slab, sidewalk, parking lot, or other hard surface, the OZ-Post 238-IS/PB delivers a fast, clean solution. Anchor the 5-3/8″ square base to your surface with appropriate mechanical fasteners, drop in a standard 2-3/8″ O.D. post, and tighten the integrated compression collar—no digging, no concrete cure time, and no messy core drilling. The hot-dip galvanized body and robust collar assembly are purpose-built for outdoor use, and field testing by OZCO shows 750 lb lateral performance when installed per guidance on suitable substrates. Installers use this base for traffic/wayfinding signs, fence terminal posts at slabs, portable barricades, and light bollard applications where speed and reusability matter.
Why Choose This
- Versatile mounting — Works on concrete, asphalt, wood decking, or welded steel plates
- Clean workflow — Drill, bolt, tighten; set the post in minutes
- Durability — Hot-dip galvanized steel resists corrosion in harsh outdoor environments

Installation
Lay out locations and verify substrate integrity. Mark and drill anchor holes in the slab/plate per the 3-1/2″ square pattern. Anchor the base with appropriate fasteners for your surface (e.g., wedge anchors for concrete, asphalt anchors for blacktop, structural screws/bolts for wood, or bolts/welds for steel plates). Insert the 2-3/8″ post fully into the collar, tighten the compression collar to lock the pipe, and complete your sign or fence hardware assembly. Always follow local codes for post height, wind loading, and anchor selection.

Buying Guide
- Surface fasteners: Choose anchors rated for your substrate and load (sold separately). See our Bolts & Fasteners and galvanized carriage bolts.
- In-ground alternative: For no-dig, in-soil installs of 2-3/8″ posts, consider the OZ-Post IS-600.
- Project type: This base excels for signs and slab-mounted fence terminals; sustained vehicle impacts or high bollard loads may require engineered bollard systems.
Frequently Asked Questions
- Does this include bolts to attach to concrete or asphalt?
- No. Surface fasteners are not included so you can select anchors appropriate to your substrate and load.
- Will it fit standard chain link terminal pipe?
- Yes. It’s sized for 2-3/8″ O.D. round posts (typical chain link terminal size).
- What loads is it rated for?
- OZCO lists up to 750 lb lateral load when properly installed on suitable substrates; always follow local code and engineering requirements.
- Can I remove and reuse it?
- Yes. The base can be unbolted and reused for temporary or modular projects.
- What’s the base bolt pattern?
- The 5-3/8″ square base uses a 3-1/2″ square hole pattern (four holes).
Comparison
| Option | Strengths | Considerations | Best For |
|---|---|---|---|
| 238-IS/PB Base (this item) | Fast surface mount; reusable; galvanized steel; tested 750 lb lateral | Requires drilling and appropriate surface anchors | Signs, slab-mounted fence terminals, modular barriers |
| IS-600 In-Ground Anchor | No-dig, in-soil installation; no slab needed | Not for mounting on hard surfaces | Chain link and wood fences in soil |
| Concrete-set Post | Traditional method; customizable footing | Excavation, cleanup, cure time | Sites where code/engineering specifies poured footings |
