Simply insert it into the weight stacker and gradually add weight to the sleeve as needed for your workout. Enhance your workout and easily achieve your fitness goals. - Package Content: Package includes a weight stacking pin and a spring ring. The weight stacking pin sleeve is long enough and designed to fit a 2 inch Olympic weight plate to add extra weight. If your machine can no longer expand the weight on its own, it's much better to use our weight stacking pin than to buy a new machine. - Premium Quality Materials:Weight stacking pins are made of sturdy solid steel for safety, reliability, resistance to bending and long life. Up to 130 pounds of extra weight can be added to the equipment to ensure that your muscles are constantly being challenged in new ways! - Buying Guide: Our weight stacking pins are available in 5/16 inch (8 mm) and 3/8 inch (10 mm) diameter pins. Please note that the 8mm pins are for fitness equipment with a 10mm diameter and the 10mm pins are for fitness equipment with a 12mm diameter. Before purchasing, please measure the cable stacking pin diameter to select the appropriate size for your fitness equipment. - Reliable Gym Accessory: This pin extender fits snugly into the weight rack of your gym machine, ensuring a safe and stable weightlifting workout. One thing to keep in mind is the distance from the hole of the insert to the floor is appropriate to put the weight plates on. ## Technical Specifications | Specification | Value | |---------------|-------| | Color | Hanger rod length:150 mm | | Size | Rod Dia:10mm Length:110mm | | Frame Material | Metal | | Material Type | Metal | | Included Components | 1X Spring Clip Collar, 1X weight stack pin | | Brand | FNKTEK | | maximum weight capacity | 130 Pounds | | Department | unisex-adult | | Manufacturer | FNKTEK | | Manufacturer reference | chaxiaogan | | Product Dimensions | 11.94 x 7.62 x 25.4 cm; 820 g | | ASIN | B0D3KYNVHR | ## Images ![Weight Stack Pin and Spring Collar Weight Stack Extender Pin Commercial and Home Gym Accessories for Cable Tower and Functional Trainer Machine - Image 1](https://m.media-amazon.com/images/I/61MJmMzB-ZL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Frequently Bought Together - FNKTEK Weight Stack Pin and Spring Collar Weight Stack Extender Pin Commercial and Home Gym Accessories for Cable Tower and Functional Trainer Machin - PERFORMANCE PIN The Original Drop Set Pins for Gym | One More Rep with Weight Stack Pins | Instant Transition to Lower Weights for More Reps | Proudly Made in America | 5/16" Pin - Gymreapers Ankle Straps (Pair) For Cable Machine Kickbacks, Glute Workouts, Lower Body Exercises - Adjustable Leg Straps with Neoprene Padding --- ## 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.in/products/649234531-weight-stack-pin-and-spring-collar-weight-stack-extender-pin](https://www.desertcart.in/products/649234531-weight-stack-pin-and-spring-collar-weight-stack-extender-pin) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-04-29*
