Slip-on front lens cap with 74mm inner diameter. Depth is 9mm.

Made of high quality aluminium alloy.

The cap is hard, and can not hold securely just by tension since this will cause scratches. You need to apply 3 thin strips of black insulation tape over the cap edge. This will prevent scratches and provide reliable hold. This is not a defect. Just specifics of usage. We don't use a fabric padding since it tends to collect dust.

The cap was made for a Rodenstock 42mm lens, but will fit other lenses with the same front outer diameter.
