5-80 LBS Range | 1-Second Quick Dial | Alloy Steel Core

One Pair. Replaces 16 Pairs of Dumbbells.
Stop cluttering your garage with expensive iron. This massive 160 lbs set (80 lbs per dumbbell) covers your full training spectrum. Adjust from 5 to 80 lbs in 5lb increments, replacing an entire rack and over 1000+ lbs of traditional weights. Apartment-friendly, compact footprint (17.44"×8.98") with a heavy-duty PP tray that protects your floors.

1-Second Weight Change & Double-Lock Safety
Keep your workout momentum alive. Perfect for drop sets and supersets with our 1-second dial adjustment. The Double-Lock Safety System ensures plates are mechanically secured at 80 lbs. The dial only works when resting securely on the tray—making it 100% safe for overhead presses, heavy rows, and explosive moves.

My garage floor is finally clear. Having 5 to 80 lbs in a compact 17 inch tray is brilliant. The 1-second dial switch makes drop sets on lateral raises effortless. Solid alloy steel.
Tired of those cheap concrete-filled plastic adjustables that crack when tapped together. These Rendpas plates are real steel. They clink like real iron without any cheap rattle.
Tried to turn the weight selector while holding it in mid-air just to test the safety lock��completely immovable. You can only switch weights when seated in the PP tray. Smart engineering.
Did high-pulls and dumbbell snatches with the 50 lb setting. No shifting or rattling. The double-lock mechanism gives you 100% confidence overhead.
When you turn the dial, every 5 lb notch clicks into place with a crisp mechanical detent. You know without looking that the plates are locked in.
The PP trays do their job protecting the floor, but they feel lightweight compared to the massive 80 lb steel dumbbells resting inside them.
Freight arrived safely strapped, just took a little over a week to make it to my depot. Dumbbells were well greased and pristine.
Import freight clearance held the shipment for three days, but courier provided tracking all the way. Product arrived in pristine condition.
Held 80 lbs per hand for high-rep trap shrugs. The diamond knurl bit into my hands without requiring chalk or lifting straps.
Pulled 80 lbs for sets of 8 on single-arm bent-over rows. The plates remain locked tight against the collar with zero rattle or shifting. Uncompromising structural strength.
Bumped the plates against my steel rack uprights multiple times during heavy sets. No flaking paint, cracked plastic covers, or dented collars. Built for hard training.
No mushy rubber or hollow plastic sound when setting them down. They sound and feel like real heavy iron. Outstanding build quality from Rendpas.
Going from 75 lb incline press straight to 30 lb skull crushers takes two clicks. No momentum lost searching through a pile of loose iron plates.
Accidentally clattered the plates together during a set of walking lunges. No cracked plastic or loose pins. Solid, reliable gym hardware built to last.
FedEx dropped two 80 lb boxes at the bottom of my driveway. Getting them inside was a workout itself! The dumbbells are pristine and the 1.3 inch steel knurled grip feels incredible in hand.
I was terrified of adjustable plates falling on my face during flat dumbbell presses. This double-lock safety system is bulletproof. Plates stay dead rigid when locked.
Because the cradle housing length stays around 17 inches even at 15 lbs, doing bicep curls takes a slightly wider path. Not a big deal for heavy bench or rows, but noticeable on curls.
Most home adjustables have thin, slippery chrome handles or cheap rubber that shreds your palms. This handle has aggressive knurling and a thick diameter that locks your grip.
Courier held box two at the regional hub for four extra days. Annoying to look at one 80 lb dumbbell while waiting, but once the pair was united, they became the core of my home gym.
Most quick-adjust dumbbells jump 10 lbs between settings, which is too much for shoulder raises or tricep extensions. These 5 lb steps make steady linear progression possible.
Ripping 80 lbs on single-arm rows and there is zero plate chatter. The mechanical locking pins engage deep into the alloy steel core. Proper heavy-duty lifting equipment.
One of the heavy-duty plastic storage trays had a small scuff mark from transit. Customer support was quick to respond, but it is just cosmetic. Dumbbells themselves are pure indestructible steel.
I use the 70 to 80 lb settings for chest and back, while my teenage son uses 20 to 30 lbs for curls and presses. A single pair handles everyone without buying multiple racks.
The rotary dial was slightly stiff on day one. After cycling through the weight increments a dozen times with a touch of dry lube, it now twists with one hand in under a second.
Had a massive three-tier dumbbell rack taking up half a bay in my garage. Sold the rack and bought this 160 lb set. They sit neatly on a small stand and do the exact same job.
Used to own selectorized dumbbells with plastic slider pins that bent after six months. These Rendpas dials rotate internal steel gears. Much more durable mechanism.
Boxes arrived banded with nylon straps and thick molded foam inside. Weighing 80 lbs each, I was worried about shipping damage, but both dumbbells were in factory mint condition.
