Finally a kit for large holes that don't require wrapping chains or cables around the vessel.
The patch is neoprene face with stainless steel backing. The support unit and t-bolts are all stainless steel. Extra holes are provided in the patch and support unit to allow for leak puncture holes to be close to the obstruction. This kit contains

• One 13-in x 23-in patch
• One 12-in x 22-in support frame
• Four stainless steel t-bolts with wing nut combos
• 16 outer conforming bolts.
