About us

CableGuard™ is a wholly developed and owned product of (PNA) Petroflex N.A., Ltd. www.petroflexna.com   PNA was founded by Pete and Susie Shauf in 1983 in Gainesville, Texas.  The company is a leading extruder of high density polyethylene duct and accessories for the electric utility, irrigation, oil & gas, telecommunications, CATV, and data voice industries.  In 1987 Petroflex acquired Advanced Pedestals (API) and began manufacturing above-grade secondary electrical pedestals and accessories from LLDPE material for the electric utility markets.  Over the years, API branched out into molding of products for oil & gas, agricultural and irrigation markets, as well as many custom injection mold and rotationally molded products.

The sales and engineering staff at PNA can recommend the right product to meet most any application.  This may be a particular duct size, fill rate, wall thickness for a certain wire or cable, or recommended tensile or crush strengths for difficult applications.  Rigorous quality control standards are maintained on all production shifts with our on-site laboratory and QC department.  We adhere to ASTM guidelines.

The manufacturing facility operates 24 hours a day, 7 days a week.  Our lead times are followed closely by production managers, sales and shipping departments.
