FIG 11: Install one screw from the kit in the front location of the left roller bracket.
Use the right angle drill adapter and the 3/8" nut driver bit.
Make sure the bracket does not move as you install the first screw.
Other screws for the left bracket may have to be driven in at an angle as driver tool is too large.
FIG 12: Once you have one screw in place, you can elevate the roller by turning the adjustment screw.
Use the 1/2" socket and a ratchet or screw gun, but elevate the roller slowly.
This will raise the cabinet giving you a little more room for the right angle adapter to work.
BE VERY CAREFUL RAISING THE CABINET.
DO NOT STRESS THE CABINET TO THE BREAKING POINT.
By raising the roller, you may be able to get enough room to install the screws in the left bracket.
If screws can't be driven straight in, then they will have to be installed at an angle.
Make sure the bracket does not move while driving the screws in.
Install 3 more screws in the left bracket. (1 in the other single hole, and 2 side by side in the middle hole)
You can attempt to put the 4 screws in the bracket on the right side with the roller raised.
If this doesn't work there is another option to install the screws (for the right side only). (See Fig 13-16)
