Duct Spacers

APPLICATION:

Duct spacers are designed to temporarily support an array of ducts within a trench until it can be filled with grout or similar suitable fill material. They also maintain accurate duct separation and alignment, which promotes reduced pulling tension. The spacer provides for independent support and separation of each duct. Ample openings for concrete flow is part of the spacer’s modular design. Formex®’s flexible design allows you to use less trench space and grout. Optional foot pads assure specified vertical separation between the trench floor and the bottom of the first duct tier. Duct spacers produced by Formex®, in combination with vertical reinforcing rods and metal collars, provide an effective means for splaying from duct bank to vault or manhole. Vertical spreads to get over obstructions can also easily be accomplished in this manner. With Formex® interlocking module duct spacers, sweeps and bends are assembled much faster and easier, and when locked into position, they stay put.

CONSTRUCTION:

Duct spacers produced by Formex® are unaffected by extremes of temperature, and virtually unbreakable, due in part to the material used to produce them. Formex® begins with two sheets of high density polyethylene (HDPE) and makes spacers to customer’s specifications by a molding process which makes possible a rugged double wall construction with an exclusive interlocking design, eliminating the need for banding duct tier. Job studies have proven use of this spacer results in lower overall costs.
