Add versatility to your strength training routine with the Landmine attachment! Choose the version that corresponds with your power rack tubing & hole size.

The Standard version fits any rack with 5/8" holes (including our 60mm & Hydra racks) provided the tubing length or width is no greater than 3". It boasts a beefy 315lb capacity with a UHMW-lined sleeve to protect your favorite Olympic barbell as you squat, press, row, Viking Press, and twist to target different muscle groups for an explosive workout.

The Manticore version fits our Manticore racks & non-Bells of Steel racks with 1″ holes and width or length no greater than 3″. Boasting a beefy 315lb capacity, it rotates in two axes instead of one for smoother landmine workouts and locks into your rack more securely using a mag pin with UHMW protection for your rack. The inner UHMW sleeve protects your barbell and the locking pin keeps it secure so your heavy training session doesn't blow up in your face.
