SLIP SAFE SUPREME™


The SLIP SAFE SUPREME™ can be installed – and reinstalled – quickly, easily and cost effectively because it does not require concrete support in strong soil conditions.

360° Breakaway System for Mid-size Sign Supports.
Used to be that installing mid-size signs were expensive multi-day projects – dig holes, set posts, pour concrete, use crane to erect posts – then put up the signs some other day. No longer.

Cost Effective.
The SLIP SAFE SUPREME™ can be installed – and reinstalled – quickly, easily and cost effectively because it does not require concrete support in strong soil conditions. Its base post is a direct-drive unit composed of two RIB-BAKs bolted together, requiring only conventional power tools for installation. Specially designed castings are bolted to the top and bottom posts. These assemblies are bolted together with U-washers, with a keeper plate in between. All assembly uses basic hand or power tools.

SLIP SAFE SUPREME™ saves you time and money in the setup. And in most cases, the entire system is reusable after it's hit, including the base post, attachment hardware, casting and top post. Stub repair is usually unnecessary.

Exceptional Driver Safety.

SLIP SAFE SUPREME™ exceeds crash impact standards by more than 200 percent. NCHRP criteria for occupant impact velocity has established a maximum of five meters per second, with three meters per second preferred. In field tests, the SLIP SAFE™ cut the preferred occupant impact velocity in half.
