By far, the most common battery strap clip for BSA. Most early BSA numbers supercede to this one (82-9004), but please be sure this is what you need (there are FOUR that Triumph/BSA used over the years), to be sure it will work for you. Look in the store or the website, we have them all.
Stainless steel construction, unlike most others on the market. No rust, no corrosion, no worries.
