Product Description

OZ-Post® ISW-850 Steel Post Anchor — Fits 2-3/8″ (2.375″ O.D.) Round Posts — 34″ Length

• No-Dig Post Foundation — Drive-in ground anchor for standard 2-3/8″ O.D. steel posts; set terminals, corners, or sign posts without digging or concrete
• Deeper Embedment vs. 24″ Models — 34″ overall length with a ~5″ top sleeve for added depth and stability on taller/windier runs
• Hot-Dip Galvanized Steel — Heavy steel, zinc-coated for long outdoor service; compression cap locks the pipe at grade
• Fast, Clean Installs — Drive with a manual or jackhammer driver kit; no forms, no cure time, minimal mess
• Field-Proven Performance — Manufacturer testing cites up to 120 mph wind-load for privacy fencing when properly installed (site and code dependent)

The OZ-Post ISW-850 is the go-to 34″ steel post anchor for 2-3/8″ O.D. posts—the standard terminal size in chain link. Its deeper embedment and wide fin profile help transfer loads into the soil, making it a favorite for privacy fences on steel posts, long straight runs, and exposed sites. Installation is straightforward: drive the anchor until the sleeve is at grade, insert your pipe, then set the compression cap to clamp the post tight. Typical installs take minutes per post and can be done in many soils—including compacted ground and even asphalt—without excavation or wet concrete.

Why Choose This

• Speed & consistency — Drive, drop, clamp; repeatable results that keep projects on schedule
• Cleaner jobsites — Minimal disturbance and no concrete washout
• Durability — Hot-dip galvanized body and elevated post base help mitigate corrosion risks

Specifications

Installation

Lay out post centers and call 811 to locate utilities. Using a manual or jackhammer driver kit, drive the ISW-850 to grade keeping it plumb. Insert the 2-3/8″ pipe fully, verify plumb, then set the compression cap (cap-driving tool recommended) until the post is clamped snugly. On rocky or bedrock sites, pre-drilling may be required; through asphalt is often feasible. Always follow local code for post spacing, height, and wind exposure.

Buying Guide

• Choosing depth: Pick ISW-850 (34″) for taller/windier lines and general soils; for hard-packed soils or asphalt where a shorter, thicker fin can help penetration, see IS-600 (24″).
• Surface-mount alternative: Setting posts on slabs or wood/steel surfaces? Use the 238-IS/PB surface base.
• Tools: For fast, consistent cap setting, add the CDT-07 cap driving tool.

Can it be driven through asphalt?
