There is a word we us a lot around the Fringe Sport office, that is not often used in the "normal" world.


What is a stringer and how does it help me install a pull-up rig?

What is it?

A secret agent? Stringer, John Stringer. License to kill.


Something to do a with a rope, a battle rope perhaps?


Some advanced Olympic Weightlifting movement?


A stringer is a board mounted horizontally and screwed into studs, that something else is then mounted to.

For example, stringers are used in home construction to provide more support or strength for stair installation, or bathtub installation.

Here's an example of a stringer used to support a bathtub. You can see the studs that the stringer is screwed to, since the drywall is removed in this pic:

In our strength and conditioning world, a stringer is used to mount a rig, squat rack, or pull-up bar to a wall or ceiling.

Here you can see a stringer used in my garage to mount a wall-mounted pull-up rig to the wall:

In the above image, the stringer is mounted outside the drywall- this is normally how stringers are used when they are used to mount wall mounted rigs and racks.

Here you can see two stringers used to mount a retractable squat rack to a concrete wall in the Fringe Sport retail location:

Why do we use stringers to mount pull-up rigs, squat racks, and pullup bars?

Stringers increase structural strength in many cases- for example, spanning studs with a stringer, then mounting a rig into the stringer makes for a more secure installation

In other cases, stringers allow you to mount into wood instead of concrete or masonry. When you screw a pull-up bar directly into concrete, the stress and vibration of the pull-up bar can pull out the mounts over time. Installing a stringer first, and then screwing into the stringer minimizes this problem.

Finally, stringers can also help you install into studs when your studs are installed in non-standard spacing. Studs are generally installed in 16 or 24 inch intervals, but some older construction does not adhere to this spacing paradigm. In this case, you would install your stringers into the studs, then your pullup rig into the stringer.

How do you install a stringer?

  1. Get the stringer. We typically recommend a 2x10" stringer for wall mount pull-up rig installation (with the length depending on the length of your wall-mount rig), two five foot long 2x6" stringers for our retractable pull-up racks, and usually 1-2 2x4" stringer(s) of about four feet in length are good for pullup bars. You can find this lumber at your local home supply store.
  2. Find your studs. With a stud-finder.
  3. Position the stringer where you want to install it.
  4. Drill through the stringer and into the studs behind it.
  5. Using lag screws, screw the stringer into your studs. Make sure you are going into the studs and not only drywall.

For installing pull-up rigs and wall-mount squat racks, you want to screw into at least 2 studs, and 3-4 is better. If I am installing a 2x4" stringer, I usually use one lag screw per stud. For a 2x6" or wider, I usually use 2 lag screws per stud.

What do you do once the stringer is installed?

  1. Now you install your gear into the stringer, using lag screws
  2. Position your gear where you want it installed and mark where to drill holes.
  3. Drill pilot holes.
  4. Screw your gear to the stringer using lag screws and a ratchet set
  5. Test your gear to make sure it is stable and installed well
  6. Do some pullups, then have a glass of milk
