Effective 3-1-2025
Metal weights for 40 foot Kits will no longer be included in our Kits.  We will include a pair of resin castings designed to hold 1/2"-13 standard hex nuts (.750" across flats).
1/2" hex nuts are available at any hardware store.  For non US customers, this size is equivalent to a M14 size nut.
Other alternatives for weights are listed below.
Lead Sheet:  Available online, Amazon, McMaster-Carr.
Lead Shot:   #9 size works well, any hardware store.
30 Foot and 50 Foot Kits will continue to include metal weights while supplies last.We recommend clear silicone or canopy glue to mount the resin castings to the Kit frame and the hex nut to the casting.
