[ IMPORTANT FRAMELESS DOOR AND INSTALLATION WARNING ]
Bally and Silicone Disaster: When installing a new Mercedes W117 Door Seal Velvet, applying Bally, Dayson, or black silicone to the metal housing is the greatest betrayal to the body paint. These seals contain a self-tensioning metal skeleton; they hold tightly to the metal flange by being pressed (inserted) without any chemicals.
Hose Pulling Tactics: The frameless (without a frame) door windows of the CLA series press directly against this seal to cut the wind. Inserting an aquarium hose into crushed seals that are allowing wind noise causes the window regulator to struggle while pushing the glass up and can lead to the window motor burning out. The definitive solution is to replace the worn seal.
The vital insulation piece that completes the aerodynamic design of Mercedes' legendary coupe-sedan, the CLA Series W117, and sharply cuts the contact of that famous "frameless door" structure with the outside world; the A-Quality imported Mercedes W117 Door Seal Velvet has arrived! This rubber barrier, which provides insulation by closing directly over the frameless door glass and adds a premium touch to the interior with its original velvet (flock) coating, gets crushed by the constant friction of the glass, UV rays from the sun, and the wear of the years. An old Mercedes W117 Door Seal Velvet with flattened rubber and shedding velvet will let unbearable wind whistling into the cabin the moment you exceed 100 km/h with your CLA and will leak water inside during pressure washes from the edges of the glass. To free your vehicle's sporty spirit from this worn acoustic vulnerability and regain that legendary German silence, you can reset your door insulation with this brand new Mercedes W117 Door Seal Velvet, produced with the original thickness. Thanks to its flexible metal spine, which locks millimetrically to the body sheet, and its soft velvet texture that meets the glass smoothly, this product will give you back that legendary vacuum feeling the moment you close your CLA's door.
Acoustic Insulation Special for Frameless Glass A brand new Mercedes W117 Door Seal Velvet has the fullness that the frameless door glass can fully press against. It cuts the wind whistling and road noise at high speeds.
Original Velvet (Flock) Texture The surface that the glass rubs against and faces the cabin is covered with premium velvet. It does not squeak when the glass goes up and down and provides luxurious integrity with the interior trims.
Clipless Metal Spine Inside the rubber structure of the product, there is a U-shaped metal skeleton. It is mounted directly to the body sheet by being pressed without any adhesive.

Frequently Asked Questions (FAQ)
My CLA has a lot of whistling/wind noise at high speeds. Does this Mercedes W117 Door Seal Velvet eliminate the noise? In vehicles with frameless doors like the CLA, there are two main reasons for wind noise: First, the crushing of the seal, and second, the glass not pressing up enough when closed (glass adjustment weakness). A brand new, full seal will largely reduce the noise as it will close the gap between the glass and the body in its original form. However, after installation, your technician should also adjust the "window regulator height and camber" from inside the door to ensure the glass presses tightly against the new seal for a 100% flawless result.
Is the product compatible with rear doors, is there a difference between left and right? Can I install it myself? There is no distinction between left-right or front-rear in seals; due to their flexible and bendable structures, they easily take the curve of the door sheet they are installed on. The product is sent in a roll; it is tightly fitted by pressing against the surrounding sheet of the door, and the excess part is neatly cut with a utility knife at the joint point. Since it does not require adhesive, users with manual skills can easily perform their own replacement with the help of a plastic installation tool.
