Telespar® Square Sign Supports
The Telespar system consists of square, perforated, welded steel tubing, in various sizes and gauges. Perforations or knockouts on all four sides allow you to mount signs back-to-back and on adjacent sides.
The unique manufacturing method used to produce Telespar tubing permits tubular sections of different sizes to telescope into the next larger size making adjustment, reinforcement and splicing fast and easy. The square shape also provides superior windload capabilities and torsional stability.
Telespar tubing is complemented by a variety of compatible fittings, accessories, nuts and bolts, and simple installation tools, creating an engineered system of integrated parts. Consider Telespar® for use as Type III barricade brackets.
The Telespar Sign Support System offers all these features:
- Easy, safe installation by hand or power
- Convenient sign mounting before installation
- Superior torsional strength
- Versatile, four-sided sign mounting at any height
- Fast, economical replacement of damaged sign posts
- Reusable materials
- FHWA-approved yielding capability
The Telespar was the first system to be used effectively in a yielding breakaway concept for small sign support systems. It is in compliance with AASHTO specifications.
