With up to two times the strength of wood, our PUPI® Series 5000 fiberglass crossarm allows for single sided H-Frame designs resulting in streamlined construction, more efficient installation, and reduced costs.
H-Frame designs using a single PUPI crossarm are more resilient and lighter weight than traditional double sided, wood H-frame construction. Our optimized designs reduce the total number of components crews need to install, reduce complexity of installation, and increase efficiencies from inventory to installation.
PUPI single sided H-frame systems have been extensively tested and shown to exceed RUS strength requirements for TH-10 V4 construction by 21%.1
PUPI’s optimized H-Frame designs can reduce assembly weight by over 50% and dramatically increase ease of installation.

|RUS Frame Type||Series 5000 Crossarm Length (FT)||Ultimate Verticle Load (LBS)||Assembly Weight (LBS) 2||Deflection (IN/1,000 LBS) 3|
1 Calculations derived from the strength requirements provided in RUS specification T-7 for wood, double arm TH-10 V4 construction of 14,000 LBS.
2 Assembly weights do not include X-Braces. Traditional 32’ TH-10, fully braced, wood double crossarm construction weighs around 1,000 LBS.
3 TH-1 and TH-1A designs do not include knee-vee braces.
