RJ-45-BYB 4,500 Lb. Capacity, Rolling Bridge Jack
BendPak RJ-45-BYB 4-post bridge jack
The RJ‐45‐BYB rolling bridge jack rolls along the entire length of the lift so you can safely raise any part of the vehicle. Rolling bridge jacks offer you versatility and increased productivity.
    The BendPak RJ‐45‐BYB air‐hydraulic rolling bridge jack is engineered and designed exclusively to fit Backyard Buddy™ four‐post lifts. This compact 4,500 pound jack equipped with modified rollers and frame assemblies retracts to a low 3.5” height from the top of the runway surface to accommodate low riding vehicles. The RJ‐45‐BYB rolling bridge jack rolls along the entire length of the lift so you can safely raise any part of the vehicle. Durable urethane contact pads and stackable adapters safely support a variety of chassis lifting points. Automatic safety locks ensure safe operation. Each RJ‐45‐BYB includes two rubber contact pads and two stackable adapters. Add a Specialty Adapter Kit for even more versatility. Specialty Adapter Kit includes: (2) Sliding Pads and (2) Sliding Receivers.

    BendPak bridge jacks are designed to be there when you need them and gone when you don’t. Just remove your RJ-45-BYB out of the way when you want the vehicle tires back on the lift.
