50mm Binocular/Monocular Objective Lens Cover Rubber Set 61mm fits models with Outer Diameter 61.5 64mm

【Measuring】Please measure the Outside diameter (including armouring) of the barrels to get accurate sizing, if the tubes outer diameter is between 61.5-64mm, it will fit perfect. If the diameter is different, please choose a different size. The internal diameter of the rubber cap is 61mm, however we suggest the outer barrels diameter is a minimum of 61.5mm to ensure the cap is not loose. 【Fits Models】Fits several 50 and 56mm models including 8x50 10x50 12x50 8x56 10x56 12x56. These covers also fit several binoculars / monoculars with objective lenses between 48-58mm as well as some scopes. 【Protection】These covers protect your lenses from rain, dust and scratches in any weather or environment. They also offer protection to your lenses in transit and storage. 【Easy to Remove / Add】Place the lens covers on the outside barrel of your binocular/monocular to protect your lenses. Covers remain attached to the binocular barrel and hang down when in use. 【Design】High quality flexible rubber is independently tethered and stretches for a tight fit. This ensures optimal protection for each lens.
