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

A 90° banger and a 45° banger side by side.

	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

On some bangers here the angle is a choice on the product page, not a separate product. In 14 mm male, the 2 mm standard banger, the Monark quartz banger, the pinch bucket and the hollow foot auto spinner each come at 45° and at 90°. Some come at one angle only: the terp vacuums here are 45°, and the 4 mm standard banger is 45° in 14 mm.
