Tools Required:
(2) Chains
• W
ARNING: Risk of fire or electric shock. Install this kit only in
luminaires that have the construction features and dimensions shown
in the photographs and/or drawings.
(2) “L” Brackets
(4) 8” UNC Self Tapping Screws
• W
ARNING: Risk of fire or electric shock. Luminaire(s) wiring, ballasts,
or other electrical parts may be damaged when drilling for installation
of reflector kit hardware. Check for enclosed wiring and components.
(2) Chain Boxes

T he SRK series (Strip Retrofit Kit) is designed to fit any existing fluorescent strip housing (4” – 4-1/2” width) with end plates, made by any
manufacturer; however, H.E. Williams, Inc. suggests installing the kit on one of the existing fixtures to check compatibility before beginning a
complete retrofit. Remove the wireway cover, sockets, and ballast(s) from the existing fixture so that only the empty channel and end plates
remain. Install as follows:
1. Install lamp socket at each end of the SRK wireway cover.
2.Feed the small end of the ball chain through the keyhole slots in
the wireway.
3.Attach “L” brackets into existing channel with self-tapping screws.
Position according to fixture length.
1.Separate upper and lower halves of the end plate
by bending repeatedly.
2.Attach the lower portion of the end plate to the wireway cover
with two #8 sheet metal screws (included).
3.If overall height of fixture is 2” or less, discard top half of end
plate. If height is greater than 2”, remove existing channel end and
install the end plate with self-tapping screws.
4.Fixture A is shown with only the bottom half of end plate.
Fixture B is taller and uses both halves of end plate.
4.Raise the wireway and feed two links of ball chain into the keyhole
slot on the “L” bracket.
