45 or 90 degree banger: matching the angle to your rig

The angle has to match the way your rig's joint points. A joint that points straight up takes a 90° banger, and a joint that comes off at a slant takes a 45° banger.

	90° banger	45° banger
Your rig's joint	points straight up	comes off at a slant
The banger's neck	leaves the bucket sideways, then turns straight down	leaves the bucket at a slant
The banger's joint	points straight down	comes off at a slant
Sizes and genders	the same choices as 45°: 10, 14 or 18 mm, male or female	the same choices as 90°

When a 90° banger is the right pick

When the joint on your rig stands vertical. Honeybee Herb's guide calls this the straight up and down joint, and pairs it with the 90° banger. Most rigs here are built this way:

When a 45° banger is the right pick

When the joint leaves the rig at an angle. Several rigs here have a 14 mm female joint at 45°, and each one's listing says so:

Bangers that come in both

The angle is a choice on most bangers here, not a separate product. The standard 2 mm and 4 mm bangers, the Monark quartz banger, the pinch bucket and the hollow foot towers and spinners all come at 45° and at 90°, and the choice is on each product page. Some one-off pieces come at a single angle; the terp vacuums here are 45° only.

Angle is one of three

The joint size and gender have to match too. The joint size guide and the male or female guide cover those, and every joint page in the Fit Index is split by angle.
