Adjusting the C-clamp
The C-clamp attaches the fixture to the mounting pipe and allows you to adjust the
position of the fixture once it is mounted.
Yoke locking
knob
1. Tightly fasten the C-clamp to the yoke with the yoke bolt and lock washer
provided.
2. Place the C-clamp on mounting pipe, then tighten the pipe bolt to secure it.
3. Loosen the C-clamp pan screw and rotate the yoke to the desired position.
4. Tighten the pan screw to lock the fixture into position.
Adjusting the yoke
To adjust the fixture's position, loosen the yoke locking knob and tilt the fixture to
the desired position. Retighten the yoke locking knob to secure it.
Source Four's two-position yoke allows you to modify the overall height of the
fixture in the yoke.
1. To change the yoke position, remove the yoke locking knob, then remove the
Figure A
hex bolts on either side of the fixture.
Note: Removing the hex bolts releases a nut in the
yoke channels on each side of the fixture. If the nuts
Figure B
come out, you may need to remove the barrel to
replace them.
2. Move the fixture to the desired position. (See Figure B)
3. Replace and tighten the hex bolts and the locking knob.
