Tools required:
- Hammer drill with ⅝″ (16mm) bit
- Small hammer
- ¾″ socket and ratchet wrench
- ½″ socket and ratchet wrench

- Place case on surface, align to desired position. Using the base as a template, mark the four (4) holes to establish pattern for drill.
- Drill four (4) holes 3″ (75mm) deep using a ⅝″ (16mm) drill bit. Clean holes.
- Using a small hammer gently tap the anchors into the holes.
- Place base over the anchors. Put washer onto lag screw. Start lag screw through base hole into anchor. Use ¾″ wrench to tighten lag screw snug into base.
- Insert your sign post to the base and secure the post by tightening the two bolts on the side of the base using the ½″ socket.
Option 2 – Asphalt Anchors
Tools required:
- Hammer drill with ⅝″ (16mm) bit
- Small hammer
- ¾″ socket and ratchet wrench
