## Questions & Answers

**Q: Working in my fj cruiser 2007**
A: Here is what I did: I slit the bottom of the caps with a sharp drywall knife. Then I  taped the area where I slit it and zip tied it around the cables.  They never moved.  Happy with how these works. 1 year + and still AOK.

**Q: are they flexable for say, jumpstarting another car ?**
A: Yes! They are flexible and can easily be pulled back to charge your battery, or jump-start another car.

**Q: what is overall length?**
A: The cover is 3 1/4" from the end of the round, cable opening to the opposite flat side.  Also, it is 1 5/8" across the shorter flat side and about 3/4" tall.

**Q: does this fit 2010 jeep liberty sport 4wd**
A: these  covers  are intended for new  cables   as  u  need to remove the ends before u can  slip them over  the cable ,  but   do  fit  wonderfully  on  new top post   clamps n!!!!    mine  i  used to make new battery  cables run to a  second battery  to power  my  4500 watt power inverter  now i  have instant   house type  power available  anywhere my  truck can go  !!(and thats a lot of  places !! ) even  away on the trails !!
