The Car Door Glass assembly is designed for straightforward installation and long-term reliability, ensuring that your C7H maintains a quiet, comfortable cabin with clear visibility in all weather conditions. This Car Door Glass set is the definitive choice for owners seeking genuine quality and perfect fitment.
This weatherstrip is mounted on the exterior of the left door to seal the gap between the glass and the door frame. It prevents water, dust, and wind from entering the cabin while allowing smooth glass movement. Manufactured from EPDM rubber with a flocked lip, it maintains flexibility across a wide temperature range.
This is the main glazing for the left door, made from high-clarity tempered safety glass. It is precisely shaped to fit the window frame and offers excellent light transmission with minimal distortion. The glass is treated to resist scratching and UV degradation, ensuring long-lasting visual quality.
This long weatherstrip is fitted on the inner side of the door glass, providing a secondary seal that complements the outer strip. It effectively blocks noise and drafts, contributing to a quieter cabin. The long version covers the entire length of the glass run for complete sealing.
The left window frame is a structural component that holds the glass and provides a mounting surface for the weatherstrips and regulator mechanism. Made from corrosion-resistant steel with a durable coating, it ensures precise alignment and smooth glass operation throughout the vehicle’s life.
This is the symmetric counterpart for the right door, offering the same sealing performance as the left side. It ensures consistent protection against the elements on both doors, maintaining the cabin’s integrity and comfort.
Mirroring the left glass, this right-side glazing is also made of tempered safety glass with the same optical properties. It fits perfectly into the right window frame, ensuring uniform visibility and safety across both sides of the cab.
The right window frame is a symmetrical version of the left, designed to support the right door glass and its associated sealing components. It shares the same robust construction and corrosion protection, ensuring long-term durability and precise fit.
These screws are used to secure the window frames and other components of the Car Door Glass system. The button head provides a low-profile finish, while the hexalobular (Torx) drive allows for high torque transfer without stripping. Made from zinc-plated steel, they resist corrosion and provide reliable fastening.
The Car Door Glass is manufactured from tempered safety glass that meets ECE R43 standards. In the event of breakage, it shatters into small, blunt pieces to reduce injury risk. The glass also offers high impact resistance against stone chips and road debris.
With both inner and outer weatherstrips, the Car Door Glass system provides an exceptional barrier against water, dust, and wind noise. This dual-seal design significantly reduces cabin noise levels, enhancing driver comfort and concentration during long hauls.
Every component in this Car Door Glass kit is manufactured to the exact dimensions of the original parts. This ensures a hassle-free installation without the need for modifications. The included tapping screws make mounting the window frames straightforward and secure.
The glass and weatherstrip materials are formulated to resist UV radiation, preventing yellowing, cracking, or loss of flexibility over time. This ensures that your Car Door Glass maintains its clarity and sealing performance for the entire service life of the vehicle.
