A quick and to the point video on using joint bumpers! A few things to remember:-less angle it will dart/ glide, more angle it will be choppy and sporadic!

-If it's nosing up unscrew the top screw eye out a half a turn at a time or the bottom one in

-If it's nosing down do the opposite, the top screw eye in or the bottom one out

The versatility and adjustability of this glide is absolutely crazy!
