The Hoist CL-3401 is a commercial selectorized leg extension machine that trains seated knee extension only. It suits health clubs, hotel and apartment gyms, studios, and homeowners who want a dedicated quad station on a low, quiet Club Line frame that keeps a training room open and easy to supervise.
Almost every listing for a leg extension machine for sale answers the space question in two dimensions: length and width. Height goes unquoted, because on most strength equipment the frame has to be tall. A pulldown needs a tower above your head. A shoulder press needs the arc.
A leg extension needs neither. The whole movement happens at seat level, between your knee and your ankle. Nothing about the exercise asks the frame to stand up—only the resistance does, and that is a design choice the manufacturer makes for you.
Hoist made it deliberately. The Club Line was built for club owners who wanted a smaller, quieter option, and Hoist holds the same low frame height across most of the line, including its 200 lb machines. So the CL-3401's stack sits inside a frame that stops below the eye line of a standing adult.
How much space does a leg extension machine need? Plan the published footprint plus room behind the seat for the leg arc and room beside it to get in and out. What the CL-3401 changes is the vertical half of that answer: it does not wall off the part of the room it stands in. For the broader selection logic, our leg extension buying guide walks through stack sizing and loading styles.
Quiet follows the same design. The Slide Select system carries no guide rods and no selector pin, which removes the friction points where stack noise usually comes from, and Hoist states the line runs quieter as a result. That matters in a hotel gym sharing a wall with a guest room or a basement under a bedroom.
Choose the CL-3401 when the leg station has to sit inside the room, not around its edges.
Three things change between users, and only one of them carries a number.
That last step is the one most machines make you do manually. The roller pad here self-adjusts, so there is no ankle number to record and nothing for the next user to inherit wrongly. The counterbalanced exercise arm stays where you left it while you get seated, and the gas spring takes the weight of the back pad so the change happens without standing up.
Is a leg extension machine worth it? It earns its floor when a room already presses and squats and still has no way to load the knee directly. If you are weighing that against a combination frame, our comparison of leg extension versus leg curl training sets out what each side actually trains.
Everything below comes from Hoist's own specification sheet and owner's manual for this model.
Hoist covers manufacturer defects under normal use or service and reserves the right to change specifications, design, and function.
Hoist sells three ways to train knee extension, and they are designed around three different problems: fitting two movements onto one stack, changing how the seat moves during the rep, and fitting the room the frame stands in.
The HD-3400 combination frame is the cheapest of the three and the only one that also curls. The Roc-It RS-2401 costs most because its seat travels with you through the rep. Ask our team to price all three against your floor plan before you commit to the space.
A good fit if you are:
Look elsewhere if you:
Two gaps are worth stating plainly. Hoist publishes no user weight limit for this frame anywhere—not on the spec sheet, not in the manual—and no crate dimensions exist for it either, so confirm delivery access with us before scheduling freight. You will find the CL-3401 alongside its siblings on our selectorized leg machines page and the heavier Club Line leg press CL-3403 if the room needs a compound station too.
Does a 300 lb stack mean 300 lb at the leg pad?
No. The hoist's own weight ratio chart for this machine puts 60 percent of the setting at the pad, so the top position delivers 180 lbs. Compare that figure, not the stack figure, against what your users actually extend.
Is a larger weight stack available for the CL-3401?
No. Hoist publishes no add-on weight kit for this frame, and the Club Line leg press is the only model in the line offered with a heavy stack. What you order is what the machine holds for its life.
What user weight is the CL-3401 rated for?
Hoist does not publish one. No figure appears in the specification sheet, the owner's manual, or the Club Line brochure, so we will not quote a number we cannot verify.
How long does the CL-3401 take to assemble?
The hoist gives no build time. The manual lists a ratchet wrench with three socket sizes, an adjustable wrench, a rubber mallet, a tape measure, a level, and hex keys, and finishes with a squareness check before the hardware is fully tightened.
Is the CL-3401 suitable for a home gym?
Yes, and plenty of home buyers choose it. Note that Hoist's residential warranty column does not cover the Club Line, so a homeowner receives the commercial terms above, and the manual publishes a separate lighter maintenance schedule for home use.
