Spindle and sleeves are components commonly associated with door handles or knobs. They play important roles in the functionality and installation of these door hardware pieces. Here's a description of each:
Spindle: A spindle is a long, cylindrical metal rod that connects the door handle or knob to the door latch mechanism. It acts as a central axis around which the handle or knob rotates. The spindle extends through the door and connects the interior and exterior components of the handle or knob. When the handle or knob is turned, the spindle rotates, engaging the door latch and allowing the door to open or close.
Spindles come in different lengths and diameters to accommodate different door thicknesses and handle designs. They are typically made of durable materials such as steel or brass to ensure strength and longevity. The ends of the spindle are often threaded to allow for the attachment of door handle components, such as escutcheon plates or knobs.
Sleeves: Sleeves, also known as collar or rosette sleeves, are decorative covers or collars that surround the spindle where it passes through the door. They are positioned against the door surface and provide an aesthetic element while also protecting the door material from wear and tear. Sleeves are typically circular or oval-shaped and are available in various designs, finishes, and materials to match the overall style of the door handle or knob.
Sleeves are usually installed on both sides of the door, covering the area where the spindle passes through. They can be secured in place using screws or other attachment methods. In addition to their decorative function, sleeves also help to hide any gaps or imperfections around the spindle opening, providing a clean and finished appearance.
When installing spindles and sleeves, it's important to ensure that they are compatible with the specific door handle or knob design and the thickness of the door. Proper measurements and alignment are necessary to ensure a secure and functional installation. Additionally, following the manufacturer's instructions for the specific handle or knob set is crucial for proper spindle and sleeve installation.
