How Stewart Masking Panels Operate

When Stewart masking products are manufactured in the factory, the frame systems are free standing on the assembly floor. Our technicians make sure the frames are vertically plumb with all back supports installed. Both top and bottom frame pieces are parallel verified by a multiple measurement process. This process assures that the masking panels will run smoothly in their respective tracks. 

Problems with Panel Operation at Site

Many times, masking panel frame systems are compressed into their final mounted position. Installers make the openings (apertures) too tight for the frame. This can cause the top and bottom frame members to be un-parallel. Therefore, the panels will not operate smoothly. Remember, when installing a Stewart masking system, allow for frame tolerance around the perimeter. Do not compress the frame within an opening. Also make sure the frame has not been slightly twisted or torqued. It must be vertically plumb to allow proper masking panel operation. Always install and use the factory back support bars on your frame system. They help to keep the top and bottom frame members parallel once the frame has been installed. 

Dirt or Debris in Tracks

We sometimes get calls from users that report one of the panels has become stuck and now its panel spring has been hyper-extended as a result. During the installation phase construction dust or debris has become entrapped in the tracks. This causes the panel's runners to bind within the tracks. Make sure to inspect and clean the panel tracks prior to operation. Remove any large particles or debris from the tracks. To remove dry wall dust, simply take a clean damp cloth and wipe the inner tracks. Never use lubricants in the tracks as this will entrap debris particles causing faulty panel operation. Periodically inspect the tracks to assure they are free of any debris particles.
