The Gallagher Alleyway Load Bars are for weighing livestock when used in conjunction with a weighing platform. They feature bottom feet mounting holes that extend beyond top covers for ease of bolting down. These are Gallagher's most versatile load bars, and they fit most sized platforms with slotted top-mounting holes. The Alleyway steel cargo bars are fully waterproof and can be used to weigh any size or type of animal up to the designated weight capacity.
