Handicap-accessible restroom trailers from Comforts of Home Services have a hydraulic lowering module and attached ramp to meet ADA guidelines. The units can be pulled up to a venue and set up for operation in less than 10 minutes, eliminating the need for an additional truck to carry an ADA ramp system. The module can be attached to any of the company’s floor plans for trailers at least 20 feet long. 630/906-8002; www.cohsi.com.
