Telescoping Square Tubing

Telespar Square TubingThe Telescoping Square tubing sign support system does more – and does it better – than anything else in its class. You simply won’t find better performance at any price. Yet, no other product makes available dollars work so hard or go so far.

The reason is simple. The Telescoping Square system was engineered specifically for sign support use, then perfected with the help of traffic-control professionals.

A Complete System

The Telescoping Square Tubing system consists of square, perforated, welded steel tubing, in eight sizes and three 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 telescoping 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 capacities and torsional stability.

Telescoping Square tubing is complemented by a variety of compatible fittings, accessories, nuts and bolts, and simple installation tools, creating an engineering system of integrated parts.

 

Square Tubing Sizes and Specification Table

Ground Support Options

Single Breakaway Anchor: using either manual or power equipment, a minimum 30″ section of 12 gauge Telescoping Square tubing is driven into the soil to serve as an anchor base. 1″ to 2″ is left exposed above the surface. One man working at ground level can safely and easily insert a 14 gauge signpost into the anchor base and bolt it in place. Installation time is thus kept to a minimum. Signs can be bolted onto the post before installation.

Two-Piece Breakaway Anchor: a two-piece breakaway system is easily created by adding a 12 gauge outer sleeve of the next larger size tube to the original anchor base. This additional sleeve, approximately 18″ long, provides a double wall thickness to accomplish the breakaway function. When installing in soil, it is advisable to drive the anchor base and outer sleeve together, leaving 1″ to 2″ of the assembly exposed above the surface. The signpost is then inserted and bolted into the anchor assembly.
