Multiprens brings to the heavy duty trucking industry Pressure Release Load Bars. This INNOVATIVE and ECONOMICAL Pressure Release Load Bar solves the industry’s problem of “blown out” trailer walls. This patented load bar is designed to protect trailer walls by limiting the maximum pressure against trailer walls. Inside the mechanism is a heavy-duty compression spring that allows the load bar to flex with the trailer as it’s moving.

  • Maximum pressure setting stops the bar from extending out too far
  • Heavy duty compression spring allows the Pressure Release Load Bar to flex with trailer walls
  • Pressure settings of 300 or 400 pounds can quickly be changed
  • COST LESS than hydraulic load bars
  • Mechanical to use with no LEAKING hydraulic fluid
  • Available in square or round rust resistant zinc plated tubing
  • 4” x 4” solid gripping non-marking weld-on feet
