Tool invented to help user to install a doorknob quickly and efficiently; would ensure that doorknob is positioned accurately and would be easily portable; prototype available

InventHelp announces that two of its clients, inventors from Toronto, Ontario, Canada, have designed a tool that would eliminate the hassle and tediousness involved in installing a doorknob. The inventors have created a prototype.

The LOCK MATE was developed to assist the user in installing a doorknob quickly and efficiently, and the invention would ensure that a doorknob is positioned accurately. The inventors believe that the device could save the user from having to hire a carpenter in order to install a doorknob. Additionally, the LOCK MATE would feature a compact, lightweight design for ease in storage and portability, and it is producible in versions for use with all standard door sizes.

The inventors came up with the idea based on their job experience. "As a professional carpenter, I was looking for a way to install doorknobs more quickly," said one inventor.

The original design was submitted to the Toronto office of InventHelp. It is currently available for licensing or sale to manufacturers or marketers.
