Product Description
OZ-Post® Manual Driving Kit — MDK-13 — Slide-Hammer Tool for Installing OZ-Post® Anchors
- Drive OZ-Posts Without a Jackhammer — Slide-hammer action uses gravity and your pull to set anchors cleanly
- Made for Small Runs — A practical choice for short projects or hard-to-reach spots where power tools are impractical
- Centered, Controlled Blows — Includes an HSP-T4 red hammer-spacer that aligns the driver inside 4×4 (T4 series) sleeves
- Jobsite-Ready Kit — Sturdy driver with ergonomic grip plus a carry case for transport and storage
- Expandable System — Use the corresponding spacers (sold separately) to center the driver in other anchor families
The MDK-13 Manual Driving Kit (Item 20500) lets you install OZ-Post® ground anchors using a controlled, repeatable slide-hammer motion—no rented jackhammer, no power needed. Out of the box, the kit comes with the HSP-T4 red spacer for 4×4 (T4 series) anchors; add the spacer that matches your anchor family when you’re working with other sizes. For one-off posts, tight access, or short fence/sign runs, crews appreciate the clean workflow and compact toolset.
Why Choose This
- Simpler setup — No power cords or compressors; ideal for limited-access sites
- Consistent alignment — Spacer centers the driver to help keep anchors plumb while driving
- Portable & reusable — Tough construction with a carry case for repeat jobs

Installation
Lay out post locations and call 811 to locate utilities. Place your OZ-Post® anchor, insert the HSP spacer that matches the anchor family, then slide the MDK-13 driver over the spacer. Use controlled upward pulls and downward slides to drive the anchor to grade, checking plumb periodically with a post level. For longer runs or dense soils, consider switching to a jackhammer driver for speed.

Buying Guide
- Manual vs. jackhammer: MDK-13 shines on short projects and tight spots. For large runs, step up to the JDK-10 Jackhammer Driver Kit to save time.
- Spacers for other anchors: Pair the driver with spacers sized for your anchors (e.g., HSP-T6 for 6×6 T6, HSP-T46 for 4×6 T46).
Frequently Asked Questions
- What anchors can I drive with the MDK-13?
- Out of the box, T4 (4×4) using the included HSP-T4 spacer. Use the correct spacer for other anchor families.
- When should I choose the jackhammer kit instead?
- On longer runs or in hard soils, a jackhammer with the JDK-10 kit is typically faster and reduces fatigue.
- Does the kit include a carrying case?
- Yes, the MDK-13 is supplied with a storage/carry case.
- Is any maintenance required?
- Keep the driver and spacer clean; inspect contact faces periodically and replace if damaged.
