The Americans with Disabilities Act (ADA) Guidelines for Outdoor Developed Areas is very specific about the wheelchair clearances required under a picnic table. To be fully ADA compliant, and wheelchair accessible, a public picnic table must provide (minimum) space under the table top that is 27 inches high, 30 inches wide, with 19 inches of knee clearance plus 5 inches of additional toe clearance.
The Pilot Rock UT Series and XT Series portable picnic tables include welded steel frames provided with a variety of finishes. You can also choose top/seat materials to fit your landscape theme. These materials include traditional lumber, 100% recycled plastic, aluminum, and thermoplastic coated expanded or perforated steel. The table frames include a lifetime warranty. The most popular top-to-seat configuration is an 8 ft. long top with 6 ft. long seats.
The company suggests park and recreation departments be careful of other tables that claim to be “ADA approved” or to offer “wheelchair”
