Nice ash rollers, quite a chore to make and pricy to buy, come in two halves and lash in place. Not really suitable for PVC. So best approach is to install the PVC before any terminals are fitted to the stay. The exception might be if you have a turnbuckle stud swaged directly to the stay. Then the inside diameter of a suitable bit of PVC pipe might fit over. But who remembers that?
In warm weather you can cut down one wall. I experimented with a table saw but the kerf was too big. Works best to use a hacksaw blade unsupported, just tape one end, wear gloves, or have really hard hands. Have the teeth oriented so the cut is on the pull stroke. It's amazing how quickly and easily you can go. Once cut, you can then open a bit of tube at a time, slipping the PVC pipe over the stay. Have some of that PVC solvent-cement. Dope the slit and use little bits of duct tape at frequent intervals to hold the slot closed till it cures. Peel the tapes and presto!
