The mounting extension set from Nesling is the perfect addition to the regular mounting sets. If you need more length or want to create extra space in the attachment, the chain is a good tool. This stainless steel set is suitable for triangular and square cloths of any size. With two carabiners and the chain, the extension set is perfect as an extension for attaching your shade cloth. Keep an eye on; the wall mountings, or bolts, are not included in this set and must be purchased separately.
