HandleStay Design Origin
HandleStay was initially designed to solve a problem. A new building had been constructed and the exterior doors to the rear needed to be held open when required. No solution seemed to be available on the market to allow that without having to in some way modify the doors. As a professional mechanical engineer, the inventor then set about coming up with a suitable way of holding the doors open, and the use of the door handle offered the best means of doing so.
Various prototypes ensued and once suitably functional the first latches were installed. Visitors noticed the devices and commented that they should be manufactured and offered for sale to solve the same problem for others – and so, the HandleStay was born!
Development of the HandleStay progressed, with computer aided stress analysis being undertaken to help ensure that the product was fit for purpose, along with numerous prototype iterations and empirical testing.
The HandleStay that you purchase today has been fully developed on that basis, and continues to be manufactured and assembled at the original location in the UK.
As the HandleStay has had a fair amount of effort input to reach the position that it currently is at, UK Design Registration was successfully sought for the design and issued under design number 6322740.

HandleStay Manufacture
HandleStays are manufactured with Fused Deposition Modelling based 3D printing. This offers benefits over some more traditional manufacturing methods in that components can be designed to exhibit strength, mass etc. exactly where it’s needed. Excess material is not used either in subtraction during manufacture, or within the body of the components if it serves no function. Form is also less limited by manufacturing requirements. The material utilised is PETG, which is ideally suited to the external environment that HandleStays may be installed in.
