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.
