Ultimation Jervis Webb Trolley for Unibilt Overhead Conveyor Systems, Adjustable Track Pins for Hoist, Gantry, Monorail or Jib Crane, Heavy Duty Metal for Smooth Material Handling, 250LB Capacity

This was part of my attic project.Unit is well built and the photo shows all the parts that come with it. Unit easily worked with a beam and two trolley.Unit is very well made and will last a long time.

Will use with 6ft' steel rail, to move carboys from fermentation table to chiller. Arrived in good shape and on time.

Product worked perfect for the intended project. But holy cow the packaging was terrible. It showed up half wrapped and damaged all over. It would be nice if the roller was a bit more snug. Decent product over all though.

Fits correctly and works smoothly
