CGW, December 4, 2012 Good and strong. Secure to use but need a lot of space to
install. Is a good choice for emergency requirements. Not
fit in speed bikes.
Ferdinand, April 19, 2012 I used the yoke C-clamp and arm assembly together with an
universal tablet mount (RAM-HOL-TAB-LGU) to attach a 10.1"
tablet to my plane's yoke on a 1,300+ NM flight from
Southern California to Idaho (and back) in a Cessna C-172.
The whole system is a snap (pun) to assemble: the user
connects the diamond base to mount with the provided screws
and nuts. There are three lengths of screws to accommodate
for different mounts. Choose carefully, or you'll scratch
the back of your device! Once it's done, use the knob on the
double-socket arm to release the two halves enough to allow
the 1" balls to enter the sockets. After that, use the knob
again to tighten the arm around the rubberized balls. That's
The whole setup (mount and yoke clamp with arm and diamond
assembly) held my Acer A500 tablet in place during 17 hours
of flight, including 1 hour of flight in severe turbulence.
RAM did a good engineering job on both this product and the
Pros: Metal construction nice one-hand release knob for
adjustment, with two 1" rubber-covered balls rubber-covered
balls makes the whole system rock-solid when tightened no
need to be a heavy-lifter, light thumb force is enough to
tighten the assembly rock-solid C-clamp screw makes it easy
to attach the assembly to yoke rounded (deburred) edges
prevent the metal parts from scratching the yoke column
high-quality powder coating provides long-lasting protection
and a very nice finish to metal parts. With a couple of cons
(see below) this is an engineering and manufacturing feast.
Cons (not many): 1). The arm assembly has only one spring,
so its load is unbalanced. As a result, when turning the
knob counterclockwise, the user releases either the diamond-
or the C-clamp ball, depending on which side is the spring.
If you want to release both balls at the same time (as it
was my case), you'd have to unscrew more of the knob, with
the resulting "benefit" that one of the balls (the one
closest to the spring) may escape from the arm socket.(I
suspect this unbalanced spring load is by design, and not an
2). I found that either the double-socket arm, or the rod
connecting the 1" ball to the C-clamp body is too short: the
tablet would not clear the yoke when the C-clamp is attached
to the yoke column. I had to improvise and attach the C-
clamp to the very base of the yoke back, on the soft rubber
end. Thank God for a large C-clamp opening!
3). The position of the C-clamp screw makes it so that when
the screw is fully unscrewed AND you fully rotate the yoke,
you could hit your knee with it. After doing so a couple of
times, I learned to extend my right leg in order to avoid
another encounter with the screw knob. Not a biggie, but a
J, April 5, 2010 Product is sturdy and works well. Should have bought a longer
arm... i bought the 3". If you are considering this for an
aircraft you might want to get the next size arm up.
