What this bracket isThe HB8-YK-LG-WH is the large, white
yoke mount from the CSC LED HB8 High Bay accessory program. A yoke (or trunnion) is a U-shaped bracket that captures the luminaire on both sides and bolts to a flat surface, an angle iron, a beam clamp or a structural bracket. Once the fixture is pivoted to the angle you want, the side bolts lock it there. Unlike an eye hook or an aircraft-cable drop, a yoke gives you a rigid, non-swinging installation — useful anywhere doors slam, forklifts pass, fans run or vibration would otherwise leave your
LED high bay slowly drifting off aim.
CompatibilityThe HB8 accessory chart identifies this part as Yoke Mount - Large, White, and its shaded compatibility cells cover the
200W and 240W HB8 high bays — the 240W black HB8-240W-3P-3CCT-UD and the 240W white HB8-240W-3P-3CCT-UD-WH. Smaller HB8 bodies use the small yoke, and the 300W bodies use the extra-large version, so match the size to the fixture before you order. Because it is a manufacturer part from the same ordering guide, the mechanical fit and the load path are the ones the manufacturer intended, which keeps maintenance simple and the fixture warranty intact. For the 100W and 150W range, see the
HB8 high bay 100W/120W/150W in black and the
HB8 high bay 100W/120W/150W in white, which take the small yoke instead.

The fixtures it supportsThe HB8 High Bays it holds are power selectable with three power settings per fixture and
3CCT selectable — three selectable colour temperatures of 3000K, 4000K and 5000K — on 120-347V with 0-10V dimming and instant start. The 240W model delivers up to 35550 lm at 4000K with a CRI of 81, a 90° beam angle, 6kV surge protection, 0.9 power factor, 15% THD, an operating range of -40°C to 50°C, 50,000 hours L70 life and a 5-year warranty. Housing is die-cast aluminum with a polycarbonate lens, rated
IP65, NEMA 4X, IK08 and NSF, cUL listed under E482965, and the 240W versions are DLC Premium. Each fixture ships with a 65" power cord and an eye hook in the box; the yoke is the alternative mounting method when that hook doesn't suit the structure.
Applications and documentationThink of the wall-mounted high bay over a loading dock, the beam-mounted unit angled down a rack aisle, the gymnasium fixture tilted away from the ceiling deck, the car wash or shop bay where a rigid bracket beats a swinging chain. Because the HB8 carries a motion sensor receptacle and works with the HB8 optics and reflectors, a yoke-mounted layout can still be tuned photometrically after install — for example with the
120° optic lens for the 200W and 240W models, or backed up by the
BLD-GM40D emergency LED driver where egress lighting is required. The full HB8 spec sheet, including the accessory compatibility chart, is in the Documentation tab of this page.
