Did these casters on my 18 and 22 and they work great. Set with a 1 inch 5/8 bolt & washer and locking nut. The handles were adjusted in a vice with new holes drilled to 7 & 1/4" and spacers (washers) were added between handle and smoker to make up the space lost. Basically giving clearance for your fingers. Castes came from Lowe's and handles from Genie. Added Universal BBQ Smoker gasket for TRAEGER. Got it from ebay. Been reading about different doors and adjusting the OEM door. Applied this and looks airtight.
