So, I have my bulldog. I'm going to be hammer drilling and installing these wedge anchors.
Let's get started.
So I have here all the tools that you're gonna need to install the wedge anchor.
So I have the wedge anchor. This is a 3/8" x 3" wedge anchor.
A pair of safety glasses.
Some blue painters tape.
An open-end wrench.
Tape measure, a hammer, my Bosch Bulldog Xtreme hammer drill, and a pair of safety gloves.
These are all the items you're gonna need to install this wedge anchor.
Pretty simple. Pretty straight forward.
You'll see on the bit here I put a piece of tape.
This is a 3 inch wedge anchor in length from top to bottom.
I measured this to be approximately 2 inches. You need at least 2 inches of gip into the concrete.
Typical concrete slabs are anywhere from 3, 3-1/2 inches to 6 inches thick.
If you're in a house, you can guarantee it's probably about 3 inches.
You never want to drill through your concrete and install your wedge anchor through the bottom.
Here I have 6 inches in this warehouse. So I have plenty of room.
I'm gonna go a little further. It's always good to go a little further when you're drilling the hole.
The reason is that you get dust down in the hole. So if it sinks below the wedge anchor to the bottom,
you're fine. It's no big deal.
If you don't and you only go the 2 inches, you'll have to blow the hole out and clean it.
It also allows you, if you go deeper than 2 inches, some wiggle room if you want to lower it a little more,
and not have as much thread sticking up.
Depends on your application.
So I have my tools, I have my gloves. I'm gonna put those on. With my safety glasses.
So let's start drilling a hole.
So in these racks, you have 2 holes in the footplate. We're only using one.
Typically, you don't have to use both holes. So we're going with one, and it's the outside one.
Now you'll see that these areas get a little tight in space.
So you're just gonna half to maneuver the hammer drill to get to the center.
As close as you can.
So I went down a lot more than what was marked there. Which will be just fine for me.
I have very thick concrete here.
So you'll also find that the tape can travel up on the bit. So you have to be a bit cautious of that.
In my situation, it really doesn't matter. I'm gonna get the wedge anchor and we'll bang that in there.
When you put a wedge anchor in, you'll want to bring the anchor's nut up...
...close to the top. You'll see on a wedge anchor that there's an area here that has a bullnose on it.
By having that bullnose, that allows you to hammer the top of the wedge anchor and not damage the threads.
So, it becomes pretty easy.
Okay. Then we're just gonna take an open-end wrench...
...and tighten it up now that a wedge anchor is pulling and wedging itself into the concrete.
Okay. There we go.
So I have a wedge anchor. You'll see these 3 prongs that, when you drill the hole and bang the anchor in,
it's very snug. Then when you start to tighten the nut against the washer, plate, and concrete,
it then pulls this wedge at the bottom into these prongs and then the prongs spread and lock the anchor in place.
That's the whole methodology of a wedge anchor.
