42mm Binocular/Monocular Objective Lens Caps Internal Diameter 51.8-53.3mm Rubber Cover Set Black, (51.8-53.3LC)

Once I determined the correct size, these lens caps worked very well. They're a soft rubber type material and have a snug fit, which is nice. They're a bit pricey and four (front and back) cost more than the binoculars!!

My binoculars (bought at an estate sale) had no lens caps. I think caps are a necessary accessory. After researching the options, I chose this product and it is a perfect fit: snug (so they stay in place and can’t fall off) but not so tight that they are a struggle to get off. The key to getting the right size is to measure the outside dimension, not inside. The way the heading is written, the term “inside dimension“ is most prominent so could lead to errors in choice. Elsewhere, there’s an instruction to measure the outside, but punctuation would go a long way to fixing the clarity of the main heading.

Excellent. Just what I needed to replace a lost cover on a Bushnell monocular. This is superior to the orginal cover. It is VERY snug, so it will not pop off easily like the original one that fell off. It has a nice slot to affix a tether. I only needed one; but, if somehow it becomes detached from the tether, I will have a spare.

Stock HDX objective covers are a poor design in terms of function as defined as. Easy to cap, easy to remove, and doesn't fall off. Sad for a higher quality (optically) pair of binoculars. These generic versions fit nice and are functional. Reason for 4 stars are. Price is inline with similar other sellers. Unknown durability. Relatively thin material. Unknown effects of cold weather on the flexibility of the material. Ideally slightly deeper covers would be nicer. Maybe silicone material would be a nicer option worth a few extra dollars? The HDX tubes at the objective end are not round. Deeper covers to ensure minimal if any intrusion of debris. Not a big issue. Needed objective covers for when tossing the binoculars uncased into a pack or walking around in heavy brushy areas.

Size: 32-34mm, Fits Tacticon 3x Magnifier with a 35mm objective bell perfectly.2mm thick rubber; smooth surface. Rigid enough to 'hug' the bell and stay on firmly.

These were a good fit for my Nikon Monarch 8 X 42 binoculars. Nikon no longer sells the caps. These were very reasonably prices and shipped quickly. Not quite as sturdy as the original Nikon caps but I did not expect them to be for the price.

It is well-constructed and is a perfect fit for my Leupold binoculars.

I bought these with fingers crossed for my Kodak PixPro AZ528 camera. Measuring the barrel diameter was a bit dicey, but seemed to be about 66mm. (The lens cover that came with the camera is ridiculous and falls off if you just glance at it, I kid you not!)Anyway, these totally, wonderfully solved my problem and the spare is an added bonus. The fit is perfect, reliable, and comfortable to pop off and on. Stays put unless you deliberately pop it off using the little tab. Looks great, like it came with the camera! See photos!Happy!!! 😊👍
