FEATURES & BENEFITS
- High load capacity is achieved due to the expansion coil locking into the sides of the hole, when set, to give cast-in type performance.
- High clamping load and resistance to cyclic loading result from the pulldown effect achieved through the rotation setting action of the anchor.
- Low profile hex head provides a neat finish.
- Removal is easy, clean and fast, as the expansion coil stays in the hole leaving no protruding metal parts to grind off. The bolt can even be reused with a new coil.

INSTALLATION GUIDE
1. Drill or core a hole to the recommended diameter and depth using the fixture as a template. Clean the hole thoroughly with a hole cleaning brush. Remove the debris with a hand pump, compressed air, or vacuum. 2. After ensuring that the anchor is assembled correctly (the coil tab points up the anchor), insert the anchor through the fixture. Tap the anchor down to the depth set mark, with a hammer, and stop. 3. Wind the anchor down, with an appropriately sized spanner or socket wrench, until the washer is firmly held to the fixture and stop (5 turns). Ensure washer is tight and snug fit. 4. The Boa™ Coil anchor is ready to take load. (The bolt can be removed leaving the coil in the hole. To re-insert, follow steps 3 and 4.)
