## Features

- PRODUCT USE: Weight stacking pins are suitable for home and professional fitness equipment. 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.

I ordered 2 of these and they both have their insertion pins are at a slight angle (not straight). They still do the job on my Inspire Fitness SCS (10 mm dia. X 110 mm long).
