What this bracket isThe
SL-SAL-BKT-ST-3-BK-G1 is listed in the LIGHT EFFICIENT DESIGN Solera solar accessory range as the
tenon adapter for 3" square pole. Its job is simple and important: create a proper tenon on the top of a 3" square pole so a slip-fitter fixture can be mounted, levelled and locked in place. All SL-SAL models include a standard slip fitter mounting bracket, so the fixture you already own is ready for this adapter straight out of the carton. The black finish keeps the hardware visually quiet under the fixture head and matches the black SL-SAL housings.
Where it fits in the accessory line-upLIGHT EFFICIENT DESIGN offers a full set of
solar area light accessories so the same fixture can go almost anywhere. For the SL-SAL off-grid and hybrid models the family includes SL-SAL-BKT-RP-BK-G1 (round pole bracket), SL-SAL-BKT-SP-BK-G1 (square pole bracket), SL-SAL-BKT-ST-3-BK-G1 (tenon adapter for 3" square pole), SL-SAL-BKT-RT-3-BK-G1 (tenon adapter for 3" round pole) and SL-SAL-BKT-WM-BK-G1 (wall mount bracket). Choose the tenon adapters when the light goes on the pole top, the round/square pole brackets when it mounts to the side of the shaft, and the
hybrid wall mount bracket when a building wall replaces the pole altogether. Note that the RP-SAL accessories are a separate series and are not interchangeable with SL-SAL hardware.

Fixtures and installationThe SL-SAL solar area lights this adapter serves cover real ground: SL-SAL-OG-30W-50K-SF-BK-G2 delivers 30W and 5900 lumens at 5000K with an EPA of 4.45, while SL-SAL-OG-50W-50K-SF-BK-G2 delivers 50W and 9800 lumens at 5000K with an EPA of 6.1; the hybrid versions SL-SAL-HYB-30W-40K-SF-BK-G2 and SL-SAL-HYB-50W-40K-SF-BK-G2 run 4000K at the same 30W/5900 lumens and 50W/9800 lumens. Off-grid models are powered entirely by the sun with no trenching or wiring, while hybrid models are backed up by line voltage for guaranteed light every night. Those fixtures carry a 100,000-hour rated life and operate from -4°F to 122°F, so plan the pole-top mount to match: check that the pole top is square-cut and clean, set the tenon adapter, slide the slip fitter over it, then level the fixture and aim the solar panel toward the sun before final tightening. Use a torque-appropriate wrench and confirm the pole's EPA capacity against the fixture EPA before you leave site.
Projects and documentationThis adapter is the everyday choice for parking lots, laneways, RV parks and campgrounds, equipment yards, rural driveways and municipal walkways where a new square pole is being set and the fixture belongs overhead. Contractors like it because it standardizes the install: same tenon, same slip fitter, same look from pole to pole across a site. Pair it with a
circular solar post top in 4000K or a
circular solar post top in 3000K elsewhere on the property for a coordinated off-grid lighting plan. The spec sheet for SL-SAL-BKT-ST-3-BK-G1 is available in the Documentation tab — download it for part numbers, fixture data and accessory cross-reference before you order.
