Crossfire Pro Caster insert

X Leg insert is drawn for 1/8th inch material. Cut 8 inserts and 4 caster plates to go with Everbilt Brand 4 inch Casters sold at Home Depot. I believe these plates will fit the 3, 4, and 5 inch caster. Must be welded square. Could possibly need a small weld to snug or light grinding if it is too snug.
