This beast replaces 16 pairs of dumbbells, offering a massive 5-80lb range in 5lb increments. It is the ultimate tool for heavy bench presses, deadlifts, and squats without cluttering your garage gym. - 【Pro-Grade Knurled Steel Grip】 Control heavy loads with confidence. The handle features deep, professional-grade steel knurling that bites into your palm for maximum stability, ensuring the dumbbell stays secure even during your heaviest, sweatiest sets. - 【Instant Dial Adjustment】 Don't let manual plate changes kill your momentum. Our precision dial system lets you switch from warm-up weights to heavy working sets in 1 second, perfect for drop sets and progressive overload training. - 【Double-Lock Safety Protocol】 Lift heavy with zero worry. The reinforced locking mechanism secures heavy cast iron plates firmly. Adjustments are strictly limited to when the unit is docked, preventing any accidental detachment during overhead or explosive movements. - 【Ultimate Space Saver】 Reclaim your floor space. Instead of a wall full of iron, get one compact unit (16-in-1) that fits in a corner. Includes a high-strength base tray to protect your floors and keep your heavy gear organized and ready for action. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0F4X95WLF | | Best Sellers Rank | #25,843 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #102 in Exercise & Fitness Dumbbells | | Brand Name | Rendpas | | Color | B | | Customer Reviews | 4.7 4.7 out of 5 stars (345) | | Grip Size | Medium | | Handle Diameter | 1 inches | | Handle Material | Alloy Steel | | Item Dimensions L x W | 38"L x 17"W | | Item Highlight | 80LB Weight Dumbbells w/Non-slip Grip, Dual-lock Safety, Space-saving Design for Strength Training | | Item Weight | 6.3 pounds | | Manufacturer | Rendpas | | Material | Alloy Steel | | Number of Items | 2 | | Number of Packs | 2 | | Number of Pieces | 2 | | Other Special Features of the Product | Adjustable Weight, Non-Slip | | Part Number | DUMBBELL-2026 | | Set Name | Rendpas Adjustable dumbbell set | | Style | Adjustable | | Target Use Body Part | Arm | | Unit Count | 1 Count | ## Product Details - **Brand:** Rendpas - **Color:** B - **Item Weight:** 6.3 pounds - **Material:** Alloy Steel - **Special Feature:** Adjustable Weight, Non-Slip ## Images ![Upgraded Adjustable Dumbbell Set, 25LB/50LB/80LB Weight Adjustable Dumbbell - Image 1](https://m.media-amazon.com/images/I/81BYslZLf+L.jpg) ## Available Options This product comes in different **Size** options. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/721422766-upgraded-adjustable-dumbbell-set-25lb-50lb-80lb-weight-adjustable-dumbbell](https://www.desertcart.co.za/products/721422766-upgraded-adjustable-dumbbell-set-25lb-50lb-80lb-weight-adjustable-dumbbell) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-11-12*
