The invention functions by sliding beneath a door, eliminating the physical strain often associated with positioning standard rubber stoppers. Its portable configuration is intended for a wide range of users, including delivery personnel, contractors, and office staff who frequently require hands-free access to doorways.

Currently managed by InventHelp, the device is being pitched for licensing or direct sale to manufacturers. The submission, filed under reference number SBT-2279, is part of the company's efforts to bring independent inventions to market through their Pittsburgh-based headquarters.
