Currently our house has no sliding screen door at the rear of the house for ventilation/insect proofing.
To remedy this, I bought a second-hand door frame and cut the aluminum frame to fit the space.
As it is only the frame, no screen (easy for me to fit) and no carriage or rollers at the top or bottom of the door, I need to purchase the correct rollers and carriages to complete the job.
The aluminum door frame is 20mm thick (external measurement) and 16mm (internal measurement).
As I do not have previous rollers/carriages to reference - how to I go about selecting and installing new items?
