Janssens | Lower Threshold Kit for Sliding Door(s)

The Janssens Lower Threshold Kit For Sliding Door(s) allows modification of the Foundation Frame of your Janssens greenhouse so that your door threshold is only 1 1/4" high instead of having to step over the 4 1/2" Foundation Frame. These are available in Black or Green, for a single or double sliding door opening.  It includes a full frame and a lock for the sliding door.

Note that this modification requires cutting the foundation frame.  If you are using this on a greenhouse that is not anchored to a full perimeter footing or slab, you will need to anchor/fix the foundation frame on either side of the threshold to keep everything aligned.  This is the new KSD version of the kit, with four sides.
