Re-Inventing Friction To Control Objects

My name is Ricardo Alonso, inventor & pres of R.A. Products Co., Inc. in Denver, CO USA.  My Pic

In 1996 I began improving closers for storm & screen doors.  To date, I own over 9 US Pats & Pats Pend some concerning a simple check mechanism: “The RedThing™”.  This little guy can generate incredible friction to hold a door opened, but I always felt that there was more!

My newest invention MagChek™ will create a new industry standard, the first feather touch closer projected to remain competitive with every leading brand.  Furthermore, combining these inventions could improve all the marquee devices you see.  Please enter and offer your opinion.
