Patent No. US 9,045,932

nited States Patent 9,045,932 covers the topic

of a hole seal, and more speciﬁcally, a hole seal

for use with industrial enclosures such as electrical

enclosures.

Typically, industrial enclosures include holes through

which electrical lines and other equipment can pass

through. When the holes are not in use, various hole

seals are commonly used to cover the open holes

in the enclosures to maintain the original enclosure

integrity. Many of the hole seals currently available

are not capable of centering the hole seal in the hole

formed in the enclosure.

Engineers at Allied Moulded Products, Inc. have

designed a hole seal that features a self-centering

structure that prevents rotation of the seal half

during and after installation, and ensures the seal

is in complete contact with the enclosure surface.

Now no matter what size hole seal is needed, the

enclosure hole seals have the capability to be

secured easily and efﬁciently.
