There is no way this thing will ever break. Opening is 3-1/8 inches. My power rack is a PowerTec rack, and the rack has 2-3/8 inches by 2-3/8 posts. This fits just fine. The lever arm works just fine, but if your rack is less than 3x3 you may want some sort of washer or bushing to keep it from moving (though it works fine without any modifications). I don’t use bumper plates, but if you do then you won’t be able to load much weight on there. But if you use old school iron plates - or especially if you use calibrated plates - you will be able to load a good amount of weight. The sleeve is 11 inches long. To give you a sense of it, I can load 7 of my 45 pound plates (with no room to spare) or 5 100 pound plates (with about an inch to spare). Review: It's ok, does what it needs to do.. - Had this in my cart and i couldn't believe the price it went to.. snatched it up under $10. Ya the build is ok, they didn't clean it much prior to the powder coating but it will do what it needs to do. I can't complain at all even if it doesn't get much use it still is nice to have. Fits my rack nicely with enough room to add a teflon washer on both sides to keep it from scuffing the post of the rack. I'll expect to have this re-coated as it is chipping and flaking like crazy. But for what i paid for it I really can't complain. It came well packaged and has a little weight to it 15lbs on my scale. ## Features - Fits 3" x 3" squat racks, with rack hole diameters of 5/8" or larger - Allows user to perform multiple additional exercises such as Belt Squats, Curls, Rows, or Guided Deadlifts - Replaces belt squat machines that can run up to multiple thousands of dollars - Built from black powder coated 11-gauge steel for maximum durability - Weight horn length: 9.8" ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BP1X1Y7F | | Best Sellers Rank | #29,543 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #136 in Weight Lifting Belts #201 in Exercise Machine Attachments | | Brand | Fitvids | | Brand Name | Fitvids | | Closure Type | Buckle | | Color | Black | | Customer Reviews | 4.0 out of 5 stars 295 Reviews | | Item Dimensions L x W | 30.7"L x 3.1"W | | Manufacturer | Signature Fitness | | Material | Stainless Steel, Powder Coated Steel | | Model Number | SF-LEVER1 | | Part Number | SF-LEVER1 | | Product Dimensions | 30.7"L x 3.1"W | | Size | One Size | | UPC | 810133186072 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Fitvids - **Item Weight:** 45 Pounds - **Material:** Metal - **Style:** Jammer Arms, 1st Generation - **Weight Limit:** 600 Pounds ## Images ![Upgraded Adjustable Jammer Arms, Lever Arms, Monolift Attachments Rated 600 LB Per Arm, Fits Racks at All Post Sizes and Hole Sizes, Pair - Image 1](https://m.media-amazon.com/images/I/61yZM4X1FyL.jpg) ![Upgraded Adjustable Jammer Arms, Lever Arms, Monolift Attachments Rated 600 LB Per Arm, Fits Racks at All Post Sizes and Hole Sizes, Pair - Image 2](https://m.media-amazon.com/images/I/61F7oz3i7VL.jpg) ![Upgraded Adjustable Jammer Arms, Lever Arms, Monolift Attachments Rated 600 LB Per Arm, Fits Racks at All Post Sizes and Hole Sizes, Pair - Image 3](https://m.media-amazon.com/images/I/61rixIT-L4L.jpg) ![Upgraded Adjustable Jammer Arms, Lever Arms, Monolift Attachments Rated 600 LB Per Arm, Fits Racks at All Post Sizes and Hole Sizes, Pair - Image 4](https://m.media-amazon.com/images/I/61KmpG94JNL.jpg) ![Upgraded Adjustable Jammer Arms, Lever Arms, Monolift Attachments Rated 600 LB Per Arm, Fits Racks at All Post Sizes and Hole Sizes, Pair - Image 5](https://m.media-amazon.com/images/I/71deE2z7VEL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very sturdy and great value for the money *by A***X on May 29, 2023* This product is heavy duty welded metal.

Ya the build is ok, they didn't clean it much prior to the powder coating but it will do what it needs to do. I can't complain at all even if it doesn't get much use it still is nice to have.

Does exactly what I need it to. Would be nice if they made a hole/pin model specifically for 3x3 racks. There's a little wobble, but it's not something you really notice while performing the exercise. I'm going to get all the paint off of the pin because it's such a tight fit that the paint scrapes off. Nearly cut myself on a piece scraping off. Company clearly didn't use the right paint/apply a primer. Overall, it's a nice addition to my home gym. --- ## 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.vn/products/505614186-upgraded-adjustable-jammer-arms-lever-arms-monolift-attachments-rated-600](https://www.desertcart.vn/products/505614186-upgraded-adjustable-jammer-arms-lever-arms-monolift-attachments-rated-600) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-06*
