REPLACEMENT Patio Door - Single Roller cartridge x 4

A home owner from Bradenton, FL 34209 says:
Trying to source replacement door roller cartridge for patio doors. Home Depot and Lowes suggested i contact your for replacement, as this style is off "expensive" doors (says HD guy former window contractor).

The rollers are single wheel with a spring-loaded guide at front of cartridge. Length 2 1/2" (3 1/4" with wheel up), Height 2" (with spring loaded guide fully extended) and 3/4" wide.

Your roller looks a lot like our 81-133. Please compare our dimensions to yours to confirm.
A handy person from Bradenton FL says:
Hi Paul. That looks like it. I guess I missed it surfing the Swissco website. Many Thanks! Just ordered two to confirm correct size, then will order the other 6.

Again, THANKS!
