FAQ
What is the difference between the Standard (HD) and Heavy Stack (HDG) configurations?
The Standard HD configuration includes a 215 lb. (98 kg) weight stack, while the Heavy Stack HDG configuration increases that to 240 lbs. (109 kg). The HDG is ideal for facilities serving advanced athletes or serious strength trainers who require more resistance. Both configurations share the same frame dimensions and features.
Can this machine be used by users of different sizes?
Yes. The HD-3400 features eight back pad adjustment settings specifically designed to accommodate a wide range of user heights and leg lengths. The self-aligning roller pad also helps ensure proper positioning regardless of user size, making it suitable for diverse gym populations.
Is professional installation required?
Due to the machine's weight - over 550 lbs. - professional delivery and assembly are strongly recommended. The HD-3400 ships via freight on a pallet. Please contact us at service@omahasportsandgames.com to coordinate delivery details and installation support.
What does the HOIST warranty cover?
HOIST offers one of the best warranty policies in the fitness industry. The warranty covers defects in workmanship and/or materials under normal use or service and applies to the original purchaser only. For complete warranty terms, refer to the HOIST support documentation included with the machine or available via their official support resources.
Is the optional 5 lb. weight upgrade easy to add?
Yes. The 5 lb. weight upgrade (RS-CAGE-NG-OPT3) is an add-on accessory that can be incorporated into either the Standard or Heavy Stack configuration. It extends the top-end resistance slightly for users who need that extra challenge. Contact us if you'd like to add this option to your order.
