Review on Experience Enhanced Safety with BAL 28005 Deluxe Tire Chock by Narendra Thapa

Please look at the pictures. Inside there is a set of gears on each side so the clamp opens and closes at the same speed. Notice how the gears warn/miss. This allows the yoke to open and close unevenly, I ran the yoke right between the tires. When I installed it the clamp was no longer square. This clip failure can cause it to fall out if the pendant needs to be moved for any reason. Do not buy this clip, its use is not safe.
