The Lockshank™ is an elegant solution for a common problem – enlarged knuckles. If you are over 50 or an expectant mother or someone who has had a knuckle injury, the Lockshank™ is likely to be just what you need.

Arthritis sufferers particularly love the Lockshank.

Pregnancy can also cause swelling of the hands. The Lockshank® allows women to wear their rings without risking having to cut them off in the later stages or in the delivery room.

Men who have suffered injuries in sports or work can also benefit from an installed Lockshank®.

The Lockshank® is an efficient, durable solution to these problems.

Lockshanks are available in sizes 4 through 12, with widths from 2.5 to 10.5mm. All sizes are 1.8mm thick.

One Lockshank® can be adapted to join two or more rings always worn together, or the Lockshank® can be worn alone as a wedding band. It can also be modified to a comfort-fit shape, rounded inside and out.

An added benefit of the Lockshank® is that a top-heavy ring can be made to fit tighter and remain properly oriented.

The Lockshank® solves many problems inherent with other types of expandable shanks:

• It opens fully, accommodating any size knuckle.
• It opens easily with just a fingernail.
• It stays securely latched until intentionally opened.
• All parts of the ring fit flush, with no small latches or hinges to snag clothing or irritate a wearer's hand.

Have your jeweler install a Lockshank®,
and continue to wear your cherished rings.
