SpinHandleAssembly
If you need to add a door to your existing greenhouse, this extension assembly will make rolling up a door quick and easy. We manufacture our spin handle from heavy-duty galvanized steel. The assembly can be installed on the ends and sides of most greenhouses. The 48” long extension is ideal for a 10 or 12-foot tall doorway. The universal joint allows you to roll up the door without damaging your greenhouse film. Simple installation and easy to use.
