The Geo Knight DK20A is the largest clamshell heat press from Geo Knight. Not only does it open for full access to the 16 in x 20 in lower bottom table, but it also features a convenient auto release. This amazing high-tech auto release feature makes your Digital Knight clamshell act like a semi-automatic, air operated press, without the compressor! Simply close the press as you normally do, and at the end of the digital timing cycle the press releases automatically. You won't have to worry about over-doing a shirt with the George Knight DK20A digital clamshell heat press with auto release. This auto release heat press also features the “hover” feature. This feature allows you to lower the handle without fully clamping the machine, which is ideal for curing purposes. At the end of the time cycle the press will then release as usual.

The DK20A also hosts a wide variety of other outstanding features, including a heat platen that rises above and away from the bottom table, providing better access than other clamshell presses. The frame support allows operators to slide shirts over the table with complete drape space around and underneath the loading area making it one of the most convenient clamshell designs ever.
