Bottom Roll Sliders


Bottom Roll Sliders


In contrast to the top hung sliding system, these doors take the weight off of the header and transfer it to the rollers in the bottom of the sliding panels. All of the configurations available in a top hung sliding system are also available in this bottom rolling system.

Like virtually all domestic sliding doors, this door system rides on a floor track and incorporates brush weatherstrip. Steel bottom roll sliding doors are the simplest to install and operate. Bottom rolling is ideal when you don’t want to hang the door weight on the head, a benefit for remodel projects where the header may not be engineered for top hung load. We add enough space under our bottom rail to incorporate a high quality adjustable ball bearing wheel set for smooth operation. The wheels glide on our zero-transition floor track which rises only 3/16” above finished floor and incorporates a continuous drain allowing it be installed without a step down to the exterior. Without a step or metal sill, the interior and exterior finishes can extend under the door and enhance the visual flow from inside the home to the outdoors. The transition is subtle and inviting.

The locking is only on the lead door in a multi-sash system which makes it very easy to operate. Simply unlock the primary door and you can push one or all of the doors with no additional hardware complication.

There are a number of configurations for the sliding door systems. From the ubiquitous XO (operable/fixed) sliding door to multiple glass panels and multiple screen panels which slide into multiple pockets. Our drawings show the variety of configurations that can be used and help with a sense of the wall buildups that will be needed for some of the larger systems.

Matching steel screens are a standard option. Typically our screen panels match the layout of the glass panels both in TDL divided lite patterns and function. With pocket conditions, the standard layout puts the screen sash on the interior of the glass door sash. This method best protects the screens and minimizes the track exposure to water damming and water infiltration into the pockets. When needed, screens can also be placed on the exterior side of the glass panels.

Our bottom rolling door system comes with continuous attachment flange to allow for logical structural integration and waterproofing between the door frame and the rough opening of the building. We have numerous custom installation details, including for pocket doors, which help facilitate most installation conditions.

The bottom rolling system is also easily adapted to motorized operation. The motorization takes place within the top guide track. The doors are belt driven from a drive motor that is located at one end of the system. Driver motors require an additional 14” of space beyond the jamb and will require an access panel for possible future maintenance or adjustment.
