Infinity Pull-up Spheres

Available in diameters of 3” and 5”, Rogue’s Pull-Up Spheres are simple but effective grip strength builders—popular with rock climbers, gymnasts, and martial artists. Mount a pair to the side of an Infinity rack or rig to add a unique new pull-up station, or use multiple spheres in sequence to create a customized obstacle course. Made in the USA from 9-gauge steel and powder-coated for optimal grip.

Important: Infinity Pull-Up Spheres have a thread length optimized only for the 2” depth of a 2x3" tube. If you wish to mount Pull-Up Spheres along the 3" depth of the tube or to the bottom of a crossmember, you will need to order the Monster Lite Pull-up Sphere Set .

Rogue Tip: If you’re new to this type of training, start with the 3” diameter Spheres and work your way up to the substantially more challenging 5” option.

Infinity Pull-up Spheres is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Legit. I recently added the 3" spheres to my RML-390F and couldn't be happier. I couldn't fit the monkey bar crossmember due to low ceilings so these were a great alternative. They add a great variation from the standard pull-up bar. You can also do neutral grip pull ups on these, so it makes them pretty versatile. The 3" is a great size (I am 5'7" with pretty average sized hands) to work on grip strength. My only slight 'issue' was I didn't know how tight to crank these down. There is a rubber spacer and the more you tighten the nut, the more the spacer 'crushes.' I just tightened each until they felt solid and ended up with 5 threads showing on each screw. Works for me. Oh and the quality is excellent.. perfect powder coating and solid hardware. Well done Rogue. Well done.

Rated 4 out of 5 by from Try the 3" spheres first... Having large hands, I immediately jumped to the 5" sphere -- in hindsight, given the different stresses on grip and wrist, I would recommend starting with the 3" model to build the requisite hand strength to fully utilize this piece of equipment. Build quality is first rate, though the bolt threads are showing signs of oxidation (my rig is outdoors); not a galvanized / treated piece of hardware (like the fasteners shipped with Rogue rig products); does not impact the functionality of the rig. I touched it up with Krylon / Rustoleum textured paint to soothe my OCD eyes.
