Dannmar MaxJax Power-sert PS2-58 epoxy anchor minimum hole depth

[hbus1300]

Installing a Max Jax lift in my garage that has a 4" slab that meets the published requirements. Opted to use the Optional Epoxy Grip Anchor Bolt Kit as I wanted the extra bit of security and will be removing/installing the lift and thought I might work the wedge style standard anchor loose.

Reviewed the Wej-IT specs for their PS2-58 anchor and it states the minimum hole depth should be 6-1/4". I went so far to email wej-it to confirm and got this response.

"The PS2-58 requires a 6-1/4" min hole depth. If your slab is only 4", these anchors should not be used.

I then contacted MaxJax/Dannmar support and got this response.

"Arturo Montes- Hello Jeremy, the minimum requirement is 4 inches"

There was a little more to that exchange, but they stood by 4" thick regardless of the floor thickness.

For those who have used the Power-sert PS2-58 anchors. Do they work with 4" thick concrete as Dannmar states?

Had a similar issue with bolt discrepancy between manufacturer and lift distributor. Went with manufacturers recommendation as they had the data to back up the claim.
Don’t use epoxy ones or dig and repour concrete

What did you end up doing? I could just use the standard wedge type and use a small amount of epoxy on each. Some of the older instal threads that seems like what some people did. I was just trying to be proactive with the epoxy anchors, but it seems like it would actually be worse to use something the manufacture of the anchor says isnt right for the application.

You'd think Dannmar would be a big enough company they'd be concerned about giving out bad information regarding the epoxy only type anchor.

In my case I listened to the bolt or epoxy maker. Mine was a question of torque and Greg Smith tech said to do something that was not right. You would think they had more experience then me but guess not.
I’d stick with the wedge anchors. Use a rotary drill. Make a jig so you drill straight. And go all the way though to dirt. If you have an issue you can pound it right through. No epoxy on wedge. You want that wedge to grab. The epoxy will freeze it so it won’t move. Until you torque it that is. Epoxy anchors are like 30psi and wedge are over 100. Mine were 150psi. Had 3 issues and then used epoxy as I have thick enough slab

I ended up using the wedge type.
