patio door roller

Hello,

Your roller is similar to the 81-030, but note that the height measures 1-1/8" as shown below. Take a look and see if the specifications match your roller assembly. 

The material of the wheels is a personal preference. If you'd prefer to stick with nylon, we offer the 81-228 wheels and 81-310 axle kit to install them. Thanks for posting!
