Key features

• •Inner Diameter: 42MM, Inner Height: 8MM approx. Outer Height: 8.8MM.
• •Offers reliable protection for your optics. These black plastic lens caps are designed to withstand regular use while keeping dust and fingerprints away from your valuable binocular, telescope, or monocular lenses.
• •Note: All sizes are measured as Internal Diameter (ID) of the cap in mm at the deep end of the cap near its inside surface. This is equivalent to the external diameter of the lens, including the lens housing (see the photo illustration). Please allow a small difference in measurement (eg. 0.5-1mm).
• •If a cap is slightly bigger than the external diameter of the lens housing and there is no matched cap size available for the lens, you may consider putting an adhesive cloth tape around the internal rim of the cap. This can often secure the cap on the lens.
• •Ideal for replacing lost or damaged covers. These affordable lens caps are perfect for those who have lost the original covers for their optical equipment or need additional protection for their gear.
