Preformed Flexible Conduit Loop
This Flexible Conduit Loop was designed for use in new construction or gravel roadways. The conduit is a ribbed non-metallic material providing full protection for the loop contained within. This loop is designed to be used in gravel applications being buried a few inches below the surface. A 1/2" non-metallic conduit should be used to protect the lead-in wire in drive area. The PVC loop can also be used with black top and concrete roadways. The proper installation procedures are below.
Preparation for Paving Over:
A. Flex conduit into a rectangle shape of the size ordered.
B. Choose proper location of loop and place loop on ground, keeping the "T" and lead-in wire closest to the operator.
C. Cover with a light coating of sand, dirt or gravel.
D. Protect lead-in wire by means of an additional length of 1/2" flexible conduit or rigid conduit of non-metallic material. This lead-in conduit should also be covered with sand, dirt or gravel, wherever black top would make contact.
Preparation for Concrete:
A. Follow steps A & B above.
B. Do not lay loop directly on rebar or wire mesh. Maintain a minimum of 3" from any metal.
C. When installing over rebar or wire mesh, use non-metallic stakes to suspend loop over any metal reinforcements.
Note: You may opt to wait
