Measure your joint
If you didn't already know, a "Male" jointed Quartz Banger fits
into a "Famale" jointed rig. Similarly, a "Female" jointed
Quartz Banger fits into a "Male" jointed rig. There is no easy way to
explain which joint size Quartz Banger you need, the best way is
to pull out a ruler and measure the inner diameter of your rig's joint!
