Further, does the higher priced stainless steel 81-137 offer any additional features over the plain steel 81-141, other than the stainless steel material itself. For example, does the 81-137 have ball bearings, while the 81-141 does not? Or, do both have sleeve bearings? The Swisco catalog copy does not specify.
Photo #2 that I have submitted, shows the bottom of our door with small "angle iron shaped" metal strips applied to the door bottom and wrapping around 90 degrees along the inside of the cavity that houses the roller assemblies. Fuzzy felt weatherstripping material is visible in the photo, obviously intended to ride against the ridge of the floor track. However, very little of it is remaining.
In fact, on the roller assembly not pictured, that metal w/felt weatherstripping is actually bent outward a bit, rubbing on the sides of the rollers. Does Swisco handle any replacement/repair product that can be applied to replace this worn original weatherstripping configuration? In particular, an improved product configuration?
At the top of our patio door opening, there is also a 'top header track', identical to the floor track. However, there are no roller assemblies on the top of the door. Just a smaller groove with a U-shaped steel and felt weatherstrip insert. This top weatherstrip seals along both sides of the top track's ridge, instead of like more modern doors, where the top weatherstripping rides along the outside of the door surfaces. The fact that there is a top track in addition to a bottom track made it difficult to remove the door!
While the top weather stripping is in fairly good shape, any Swisco products to repair/replace the battered bottom weatherstripping would be of interest.
I commend Swisco for providing this easy photo submission process. Six years ago, I submitted photos to Donna P. the old way, by e-mail attachment. She made it work and used it to clear up my problem immediately. So, I am glad you have now made it a routinely available to supplement customer inquiries.
