How delivery works
Your item’s shipping method and price are confirmed in the shipping calculator and at checkout. Here is what each delivery path means.
Driveway freight delivery
Your equipment is palletized and protected. The freight carrier schedules delivery, then uses a liftgate to lower it to your curb or driveway. Moving it inside and unpacking it are up to you.
Inside delivery & assembly
When selected and available for your address, the delivery team brings the equipment into the room, assembles and tests it, then removes the packaging.
Full truckload
For commercial builds and multi-pallet orders, a dedicated trailer keeps the full order together in one delivery. We confirm the unloading plan before the truck ships.
Size: 40" × 69" × 58" tall
Financing: From $174.37/mo or 0% APR with
Check your purchasing powerWhat New Means
Brand new, current-model equipment shipped in the factory crate with the full manufacturer warranty. Extended coverage is available at checkout.
Warranty Coverage
New and remanufactured equipment are both covered for one year, parts and labor, backed by us. Extended protection is available on either through BAG Care+. Used equipment is sold as-is with no warranty coverage, and is described honestly before you buy. We service nationwide - every ZIP code in the country - so coverage travels with the machine.
30-Day Returns & Exchanges
Change your mind within 30 days of delivery and you can return the machine or exchange it for a different size, color or configuration.
Return shipping is the customer's responsibility and a 15% restocking fee applies to preference returns and exchanges. Freight items must go back packaged to the same standard they arrived in — we will tell you exactly what that means before anything is collected.
Anything that arrives damaged or fails under warranty is handled separately and carries no restocking fee. Full terms are in our Returns, Exchange & Refund Policy.

Product details
Commercial-grade equipment, inspected and supported by warranty.
The BUILT Strength Fractal Series Calf Extension targets both the gastrocnemius and soleus through a seated plantar flexion movement on an angled footplate that supports a full dorsiflexion-to-plantarflexion range of motion — the deep stretch at the bottom and complete contraction at the top that calf development demands. The seated position with knees bent specifically de-emphasizes the gastrocnemius and increases soleus isolation compared to standing calf raise machines, making this the more complete lower-leg development option.
A padded seat and leg restraint maintain correct alignment and prevent the legs from shifting under load, and a 280 lb selectorized stack provides the loading range for both light activation work and serious progressive calf strength training. Compact 40" × 69" footprint, 581 lb commercial frame. New.
Primary muscles targeted
Soleus Gastrocnemius
Secondary muscles
Tibialis Anterior Peroneals
Key features
Angled Footplate — Full Plantar Flexion Range
The angled footplate positions the ball of the foot correctly for a full dorsiflexion stretch at the bottom through maximum plantarflexion contraction at the top — the complete calf arc needed for both gastrocnemius and soleus fiber recruitment.
Seated Position — Soleus Isolation Emphasis
The seated, knees-bent position reduces gastrocnemius recruitment and shifts emphasis to the soleus — the muscle most undertrained on standing calf raise machines — making this the more complete lower-leg development option.
Padded Seat & Leg Restraint
A padded seat and leg restraint keep the user correctly positioned and prevent leg shift under heavy loads — maintaining consistent footplate contact and loading angle through every rep of every set.
280 lb Selectorized Stack
A 280 lb pin-select stack provides a wide loading range for calf development — from light activation and warm-up work through serious progressive lower-leg strength training without a stack ceiling limiting progress.
