Wasp Inc. has redesigned its inverted caster bed dolly to incorporate several significant improvements. The main frame has been completely redesigned using high tensile materials to both lighten the dolly and make it more durable. The new design also incorporates features previously considered to be "extra cost" such as caster protection, fork tineways, and stops for virtually all pallets and containers. The brake system also features a "self adjusting" linkage that maintains brake pressure independent of tire wear.
