Lincoln Park 4 Lane
I did the fences with 2 different PVC angles.One is for rendering archways while the other isa window trim. The archway PVC was tacked to the track & a piece of 3mm ply used to space the angle from the track while I inserted the Screws and cup washers.The window trim PVC had the retaining side removed with a jig saw. The remaining side was inserted between the track edge and the Archway PVC . The result is a fence 40mm high that can be removed an 100 mm wide perspex fitted where needed .
