Custom Polyurethane or ABS Lens Back Cap

Description

You wouldn't leave the house without pants—so why leave your lens without a back cap?

CineBear's Custom TPU Lens Back Caps are built to protect the most vulnerable (and often most ignored) part of your lens: the mount. Designed with the same rugged Polyurethane Thermoplastic (TPU) as our lens and body caps, these back caps are made to grip tight, hold strong, and keep dust, grit, and mystery goo off your precious rear elements. Optional hard ABS plastic also available.

Like all our gear, they're fully customizable—we'll mold your focal length, T-stop, company name, serial number, or even a not-so-subtle "HANDS OFF" directly into the cap, in a contrasting color for maximum visibility.

Ready to build yours? Fire up the CineBear Designer Tool.
Head over to **Designer.CineBear.Shop**, spec out your cap exactly the way you want it—mount type, base color, lettering color, and all your custom text—then send it straight to your cart. Once the Bears get their paws on your design, they'll get to work crafting a one-of-a-kind cap or tag made specifically for you. No templates. No off-the-shelf compromises. Just your lens, your label, your way.

Mount Options Include:
– Canon EF & RF
– Sony E
– ARRI PL
– Other mounts upon request (yes, even that weird one from the back of your gear closet)

Key Features:
– Custom text molded directly into the cap—no stickers, no smudges, just clean, permanent labeling.
– Durable TPU construction that won't crack under pressure, drop, or passive-aggressive AC stare.
– Color options for both base and lettering**—perfect for color-coding your lens set or just flexing your brand.
– CineBear rental fleet-tested—if it survives our shelves, vans, and interns, it'll survive anything.
– Designed by you, built by the Bears—every cap is made to order, so what shows up is exactly what you spaced out.

Ideal for rentals, camera crews, or anyone tired of digging through a pile of mystery caps, these back caps are the pro-level upgrade your lenses didn't know they needed.

Cap it. Label it. Protect it. Sleep better at night.
