SNAP’n SAFE Round Post Surface Mount Breakaway Base
The SNAP’n SAFE Round Post Surface Mount Base is an NCHRP 350 compliant breakaway base that is designed with a 360° shear point that will prevent the sign post from striking and penetrating the windshield or roof of a vehicle when impacted during a collision.
This base will mount 8–16 gauge 2-3/8” round posts to concrete surfaces only. It is not intended to be used on asphalt surfaces due to structural integrity issues with asphalt. It weighs 12 lbs. and is made of cast gray iron, 80% of which is recycled material. It can also withstand winds of up to 120 mph.
All ground mounting hardware is included with the base. A 5/16" hex key is required to tighten the set screw that secures the round post.

SNAP'n SAFE™ Round Post Surface Mount Breakaway
This SNAP'n SAFE™ Breakaway Device is made of cast gray iron, and withstands winds of 120 MPH. Made from 80% recycled materials.
Installation instructions are included with every SNAP' SAFE round post surface mount breakaway device. It is recommended that this breakaway be installed in concrete surfaces only due to the strength of concrete as compared to asphalt.
- 5/16″ hex-key or wrench
- 9/16″ socket and ratchet wrench
- Remove any burrs or imperfections from the inside of the 2⅜″ OD 8–16 gauge round sign post
- Determine the location for the surface mount coupler. (Please note that all bolts must be at least 5 inches from all concrete edges.)
- Place surface mount coupler on the concrete surface and place the sign post on top of the coupler. Using a level, determine if any washers are needed under the base at the hole location to level out the sign post.
- Using the surface mount coupler as a template, mark the location of the three (3) holes to drill. With a ⅜ inch drill bit, drill three (3) holes at least 4½″ deep. It is not necessary to blow the holes out or clean them out.
- Clean off concrete surface and align the coupler with the holes. Place any necessary washers under the base as determined in Step 3.
- Put one (1) washer on each bolt and install the three (3) bolts. (DO NOT tighten all the way until you are certain that the base is level and all three (3) hole locations are firmly resting on the washers or concrete.)
- Note: The bolts are carbon steel and are extremely hard. They have a 3,800 pound pull-out strength.
- If using an 8–12 gauge post, REMOVE the sleeve on the SNAP'n SAFE coupler. Leave the sleeve in place on SNAP'n SAFE coupler for 13–16 gauge sign posts.
- Slide the sign post over SNAP'n SAFE coupler.
- Align the sign post to proper orientation.
- Using a 5/16″ hex wrench, tighten the set screw into the SNAP'n SAFE coupler until secured.
