Product Description
OZ-Post® HSP-HB Blue Hammer-Spacer — Centers OH-02 Driver in HB-700 Anchors
- Keep the Driver Centered — Slides over the OH-02 Oz-Hammer to keep impacts centered inside the HB-700 round anchor sleeve for smoother, straighter installs
- Cleaner, Faster Driving — Reduces wobble and bounce when jackhammer-driving HB-700 anchors, helping maintain plumb
- Steel, Powder-Coated Tool — Durable, reusable spacer; color-coded blue for quick identification in the field
- Purpose-Built Fit — Sized to bridge the gap between the ~1-1/8″ OH-02 driver and the ~1-3/4″ HB-700 sleeve I.D.
The OZ-Post HSP-HB Hammer-Spacer is the simple add-on that makes jackhammer installs of HB-700 (1-7/8″ O.D.) round anchors go smoothly. By centering the OH-02 driver inside the HB-700’s sleeve, the spacer delivers square, controlled blows, reducing sleeve chatter and helping you keep the post anchor plumb as you drive. Its powder-coated steel body is built for repeated use and easy to spot in a crowded tool bucket.
Why Choose This
- Consistency at scale — Uniform, centered impacts across long runs
- Better control — Helps minimize driver “wander” that can tilt anchors
- Jobsite tough — Steel construction with powder-coat finish

Buying Guide
- Anchor match: Use HSP-HB only with HB-700. For 1-5/8″ line posts (GB-700) or 2-3/8″ terminals (IS-600 / ISW-850), use the spacer/color that matches those anchors.
- Driver compatibility: This spacer is designed for the OH-02 Oz-Hammer. After driving, seat the compression cap quickly with the CDT-07 Cap Driving Tool.
Frequently Asked Questions
- Why do I need a spacer with HB-700?
- HB-700’s sleeve I.D. is larger than the OH-02 driver diameter. The spacer fills that gap so the driver strikes are centered.
- Will it work with hand-driving?
- It’s intended for jackhammer installs using the OH-02 driver.
- Is the spacer reusable?
- Yes. It’s a steel, powder-coated tool intended for repeated use.
- Is this the right spacer for other anchors?
- No. Choose the spacer that matches your anchor family (e.g., HSP-I3 for I3-850, HSP-I25 for I25-850, HSP-T6 for T6 anchors).
