The Safety-Splice™ Signpost System

The Safety-Splice™ Signpost System from Chicago Heights Steel delivers both Safety and Economy in an FHWA approved Base Break-Away System. It is a unique, easy-to-install, ground mounted and bolted base break-away system for any size channel, up to and including 4 lb. posts.

Other systems are based on the assumption that higher yield strength posts make one system better than others, which is not so. The Safety-Splice™ System offers a tensile strength of 70,000 PSI - exactly the right strength for break-away post systems. All this strength, vehicle impact is transmitted through the post to the splice hardware. Systems using higher yield strength posts are brittle and can fracture at the point of impact (bumper height), scraping the bottom of the vehicle or puncturing the passenger compartment, the fuel tank or both.

Ingeniously Simple Design Offers Fast Installation In Any Terrain

Though designed with the safety of both motorists and your installation crews in mind, the Safety-Splice™ System still costs considerably less than other competitive U-channel break-away systems. Because the Safety-Splice™ System uses just two special bolts and spacers to join the base to the top post, your installation crews can install more posts faster; they will spend less time working by the side of the road, thus reducing their exposure to the risk of traffic related injuries.

The Safety-Splice™ Signpost Systemsecurely nests and bolts two U-Channel posts together, yet breaks away on impact. The system has been tested and approved for multiple post installations, up to three 4 lb. signposts in either strong or weak soil (NCHRP 350). For single or multiple post installations, the Safety-Splice™ Systemstands up to a variety of wind pressure conditions and meets the new FHWA guidelines.

The System That's So Secure It's Both FHWA and AASHTO Approved!

The System That's As Easy to Install as 1-2-3!

The Safety-Splice™ Signpost System hardware consists of two high performance Grade 9 bolts and nuts, each with two Grade 9 washers and two unique spacers with easy slide-on retaining washers. These specially designed components make break-away post assembly simple and fast.

1. Dig a small, shallow hole approximately 6 inches in diameter and 2 inches deep; drive the ground post into the center of the hole leaving the top 4 inches above grade level exposed.
2. Place one bolt in the 1st and 5th holes in the ground post. Slide a spacer and push-on retaining washer onto each bolt, leaving both bolts ends exposed.
3. The top post is then nested over the end of the ground post and seated on the bolts. Lock nuts and washers are then installed and tightened and the earth around the post hole replaced and tamped firmly to complete the installation.
