Standard Features

Silicone O-rings

Hollow Silicone O-rings

The main o-ring which makes UK cases water tight is actually made from hollow silicone rubber tubing (left and center) which is chemically resistant and retains it's shape with age. Other case manufacturers often use foam neoprene o-rings (right) which lose their shape and effectiveness over time.

Silicone O-rings

Attachment Points

UK boxes have strap slots molded onto the body ends for use with attachments. We also include molded hasp loops to padlock or tie the lids closed. This prevents contents from being surreptitiously removed.

ABS Construction

ABS Construction

Our hard protective boxes are tough yet lightweight because we construct them using high-impact, field-repairable ABS resin. ABS better resists becoming brittle in cold weather and withstands heavy use.

Piano Hinges

Piano Hinges

Our protective cases feature full length hinges with a stainless steel pin for strength and durability you can trust.
