Megatron 4-Stack Jungle Gym w/ Pec/Rear Delt Combo (Heavy Commercial) Build a complete strength corner in one compact, high-output unit. The Megatron 4-Stack Jungle Gym combines four essential training stations—Pec/Rear Delt Combo, Low Row, Lat Pulldown, and an Adjustable Functional Column—into a single heavy commercial machine designed for busy gyms and serious training. Built from 11-gauge steel, finished with double-stitched commercial upholstery, and driven by aircraft-grade cables, Megatron is made to take daily abuse while delivering smooth, consistent reps. Best of all, it supports multiple users at once while taking up less space than four separate machines.
Station 1: Pec Deck / Rear Delt Combo (Quick-Change)
Get two key upper-body movements in one station—fast. The gas-assisted seat adjustment makes setup easy for all users, and the station switches from pec fly to rear delt with quick-action pop pins.
Pec fly benefits: targets the chest through a controlled arc for strong contraction and cleaner form than free weights.
Rear delt benefits: builds shoulder balance and posture support, helping round out pressing-heavy programs and reduce common shoulder imbalances.
Station 2: Dual Cable Low Row (Unilateral or Iso-Lateral)
The dual cable design lets users row one arm at a time (unilateral) or both sides independently (iso-lateral) to build balanced strength and cleaner movement patterns.
Low row benefits: strengthens lats, mid-back, and scapular control for better pulling power and improved posture—especially valuable for athletes and general fitness members.
Station 3: Dual Cable Lat Pulldown (Unilateral or Iso-Lateral)
Train symmetrical strength without letting a dominant side take over. The dual cable lat pulldown supports unilateral and iso-lateral training so users can correct imbalances while still moving serious weight.
Lat pulldown benefits: builds width and strength through the lats and upper back, supports pull-up strength, and reinforces strong shoulder mechanics.
Station 4: Adjustable Functional Column (Nearly Unlimited Options)
The fourth station is a true versatility engine. The adjustable pulley moves quickly from low to high and everything in between, with a 6' adjustment range to fit virtually any user and movement. With a 2:1 pulley ratio, it delivers smooth resistance and excellent control for both strength work and higher-rep training.
Functional column benefits: ideal for cable presses, rows, chops, lifts, curls, triceps work, lateral raises, rehab-style movements, and sport-specific patterns—perfect for personal training, small group training, and general gym traffic.

Dual cable handles let you train unilateral or iso-lateral, so your stronger side can’t “carry” the rep. That means better balance, cleaner mechanics, and more complete back development over time.
Quick-Change Pop Pins: Pec Fly to Rear Delt
Switch from pec fly to rear delt in seconds with quick-action pop pins, so training stays efficient even during busy gym hours. Pair that with the gas-assisted seat adjustment, and you get fast setup, better fit, and more consistent reps.
Quick-Change Pop Pin Functional Column
The functional column adjusts fast from low to high (and everywhere between), making it easy to move from one exercise to the next without breaking flow. With the wide adjustment range, you can dial in the right angle for presses, rows, chops, curls, triceps, and rehab-style work.
