Conduit Cutting


ELECTRI-FLEX CUTTING VISE

A simple way to increase productivity in the contractor and industrial areas.

Time is money and thats what this ELECTRI-FLEX CUTTING VISE was designed to save. It quickly and accurately cuts conduit, raceways, etc., and that means there are no ragged ends, crushed or out-of-round conduit, or jagged bias cuts that have to be re-cut. It saves both time and materials. And its built rugged to last for years.     

 Cutting Flexible Conduits

Proper cutting methods for flexible conduits are important to ensure a sealed connection when assembled with intended fittings. Furthermore, in case of flexible conduits containing steel, a clean, square cut is necessary for establishing a good connection for continuity of the ground

Hand Cutting in field

When using a hand held hack saw, care should be taken to make a square clean cut. This can be easily achieved through the use of the cutting vise shown on this page. For best results, a blade having 24 to 32 teeth per inch with no-set is recommended. For larger sizes, apply reinforced tape around the circumference of the conduit and cut directly through the middle of the tape. This will reduce the possibility of flaring the ends while cutting.

Repetitive Production Cutting

It has been our experience that in order to archive the best results; a band saw having a blade with 24 to 34 teeth per inch at a speed of 300 to 350 feet per minute should be used. A no-set blade will produce the cleanest cut. Conduit should be held and supported in a safe manner. Abrasive cut-off wheels and chop saws are not recommended.

LAZY LOUIE LIQUATITE REEL PAYOUT STAND

Safe and easy handling of conduit for contractor and high-rise work.

This rugged, yet simple PAYOUT REEL is worth its weight in gold. It easily handles reels (24 and 30 standard or 32 special) hassle-free, and can take loaded reels of 400 lbs. capacity.

The tough steel construction of the base, roller bearings and top plate are trouble less. The tubular shaft makes set up and handling a breeze. Theres never a need of a hoist or a forklift to push the reels around. With the LAZY LOUIE you set up just where you want to work and thats it.
