Dust-Shield Rubber Objective Caps

Two black rubber objective lens caps engineered exclusively for binoculars and compact spotting scopes with objective tube outer diameters of 52 mm to 54 mm. Each cap has a precisely moulded inner diameter of 42 mm to engage the lens housing via uniform radial pressure — achieving stable, silent, tool-free attachment. Measuring ~25 mm tall with ~2.5 mm wall thickness, they fully enclose the front lens rim while allowing natural downward suspension during use. Made from dense, low-tack rubber, they resist dust infiltration, light impact, and incidental contact during packing or handling. Lightweight at just 8 g per unit, they integrate seamlessly into existing carry systems — whether clipped to straps, stored in pouches, or left mounted during transport. Validated for dependable performance across UK seasonal variability and typical field-use intensity.
