Penn Spinfisher:
DZ:
Put this power knob on my penn spinfisher 6500 live liner reel and it looks awesome!!! Only 4 stars bc it is a drill fit and a bit of a pain. If your not a patient person you won't get the install correct on this. You have to get the hole drilled out for a tight fit which i did but its a tedious process. Getting the ol rivot out was also a slow process. But end result looks awesome, fits tightly, spins very well w/ bearings- end all glad i went for it!!
Daiwa BG
Andrew Mitchell:
Be prepared to take a hack saw blade to your existing handle in order to install this knob. I used a drill press to drill out the remaining original riveted shaft starting with a small bit and working my way up to a 15/64" bit. The knob was easy to install after that and it fits perfectly. I installed this knob on a Daiwa BG 6500. It feels just as good or better as the factory knobs on my Penn slammers.
Penn Battle II
Fred Couch:
Items needed for install on Penn II: - 2 #1 phillips head screwdrivers - Locktite - Hack Saw - Drill with quite a few drill bits (cant remember exact sizes used) - A steady hand, and a willingness to start cutting away at a 150 purchase.
