Crutchfield Customer Review (What's this?)
Never hooked up an amp.to.a side post battery before this did the trick
Long enough for large terminals
Had to cut the rubber to make the post fit

Street wires battery side terminal standoff

Written By Doug E., Ortonville, MI on Sunday, June 02, 2013
Crutchfield Customer Review (What's this?)
Performed as intended to hook up an 8 AWG monster power cable with ring terminal. Only two tools needed for installation. Glad I purchased the long thread as I would probably strip the shorter ones into the battery's lead post.
Easy install. Good price.
Wish it came with washers sized to cover a blue ring terminal.

Nice side terminal retrofit!

Written By Stonecold_HTM, Overland Park, KS on Friday, April 06, 2012
Crutchfield Customer Review (What's this?)
Nice side terminal retrofit. Simply remove the stock threaded side terminal and replace with this terminal. This allows you to use your existing connection, but adds another threaded terminal end for adding other electrical connections (e.g., audio power wring). I used a small flat head screw driver to push back the rubber surrounding the existing terminal and it pops outs pretty easy.
Easy way to extend a side post for making additional battery connections
