Review on Inch Gate Caster: The Ultimate Heavy-Duty Construction Solution by David Elam

This type of compression spring and wheel is designed to support the weight applied to it without fully compressing the spring. This allows your gate to roll over uneven ground/surface and still float enough to support the gate without sagging enough to be dragged. Using a luggage scale (wrist strap with weights) I found this spring to be fully compressed at 27 pounds. Yes, this product "holds" a force of 130 pounds, but the spring is fully down and cannot "float". I replaced the original spring with a higher force spring and now the wheel keeps my gate off the ground and doesn't drag. Using the same luggage scale, I found that my gate required at least 37 pounds of force to keep it from pulling. There are higher capacity springs, but you need to be careful to match the unloaded length, spring ID/OD and especially the WLL. I could get one for less than two dollars, so the added value wasn't significant. I would be very interested to know how the "£130 valuation" is calculated.
