After many, many requests we introduced a StarPort to fit straight into this space, the StarPort HD. This is a stylish, four screw base mount, which comes with the popular RAILBLAZA locking slide, and is lower in profile than others on the market. These can be easily mounted on the Feelfree Uni Track Accessory Mount.
IMPORTANT: Use of petroleum based lubricants on the StarPort slide will cause failure. Silicone based products are best suited (please check contents of lubricant before using).
