A retractable tether from a belt clip that easily attaches to the back of any cell phone. - Tether should be 42" long. - Tether housing clips to belt. - Opposite end of tether attaches to back of cell phone by either strong suction cup or strong Velcro with plastic teeth to handle repeated detaching and attaching. - Tether needs to be able to lock in position at any length like a tape measure. - Tether housing should have 3 different mini clips on it. One on the lower face so the back of the cell phone attachment can hook to the tether housing. One on each side or the tether housing for hanging a key or a bluetooth devise. Take the basic key back or badge holder

We are looking to redesign the front cover only of our housing. The cover should keep the same dimensions so it still snaps into and works with the back housing. The back housing will be an industrial white. The front housing will be clear. See the sketch concept (MRX design version 2 - Setra file) file to see what we are moving to. We want to move away from the curved look of the front cover in favor of a flat face with a bezel (see the BAPI product for inspiration). The sticker label will have a rectangle cutout where a new, larger backlit display will be featured. The sticker will have a slight industrial texture to it. Please note we are considering adding a blue LED inside the housing to illuminate the clear edges of the front cover housing. Please try to mockup up the product with and without a blue light glow. Please also have a backlight effect on the display. All entries should be on a white or transparent background. Attached are current CAD files. Note the front cover will now have a flat face, the back housing will not change except for the color which will be safety/industrial white. Also attached are images of our current product (the MRX) and competitor products. We like the BAPI design the best. One final note, we also wanted to change the locking hinge to have more of a rounded shape instead of the squared shape. We also want to add a small hole in the latch (and a new hole in the back housing) for a small cotter key type lock or set screw. Thanks and I am happy to provide clarification.
