Janssens Lower Threshold Kit for Sliding Door(s) - VI-KSD-70-BLACK
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.

Maintenance Tips
- Clean the threshold track regularly to remove dirt, leaves, and debris that may obstruct smooth sliding door operation.
- Inspect drainage channels to ensure they remain clear and allow proper water runoff.
- Check fittings and fixings periodically and tighten any loose screws or brackets.
- Avoid using abrasive cleaners that may damage the black finish or protective coating.
- Wipe down the threshold with a damp cloth to prevent dust and soil buildup.
- Ensure sliding door rollers align correctly with the threshold for smooth movement and reduced wear.
- Inspect for signs of corrosion or damage and treat exposed areas promptly.
- Keep the surrounding floor area clean to minimize debris entering the track system.
