How it installs
Drill a hole with a 1-3/4" (SDS MAX) bit, as deep as the anchor (11.5″), using a hammer drill.
Clean the hole: brush, blow, brush, blow.
Fill the hole with EPX2 or EPX3 adhesive. The adhesive calculator tells you how much.
Insert the anchor until it sits flush with the pavement.
Wait for the adhesive to cure (follow its cure time; longer in the cold), then bolt your post down.
About this anchor
Built so the anchor is never the weak link
The HD75 is for installs where the hardware takes the abuse: bollards that get nudged by bumpers, fences that get backed into, speed bumps that trucks roll over all day.
We made it to use a 3/4″ bolt and to replace the welded construction of our SP series, which in the toughest jobs could make the anchor itself the weak point. The HD75 is CNC-machined from about a kilogram of 304 stainless billet, so sudden hits, repeated loads, vibration and shock have much more metal to work through.
What it won't do
It won't grip the asphalt harder. Our SP anchors already hold to the physical limit of the pavement, and no anchor can change what asphalt can take. What the HD75 changes is what fails first: it gives you a much larger margin against wear, repeated impacts and long-term vibration, so the anchor isn't the part that gives out.
Choose the HD75 when
- Something will get hit over and over: bollards, guard posts, fencing
- Heavy vehicles run over it: speed bumps and humps, especially with trucks
- There's constant vibration or shock
- You need a 3/4″ bolt
For most bollard, fence and speed-bump installs, the SP58 is still a great fit. Choose the HD75 when the anchor can't be the weak link.

Questions
EPX3 or EPX2?
EPX3 is the better adhesive in every way and works in cold weather. EPX2 is an anchoring cement whose advantage is cost; use it at 45°F and above. We recommend EPX3 when it's typically below 45°F near you this time of year, and EPX2 otherwise.
Do I need the CG40 caulk gun?
Only if you don't already have a high-leverage or electric caulk gun. EPX3 needs a high-thrust gun to dispense.
