How to Measure Glass Accessories for Your ROOR®
Choosing the correct accessory starts with proper measurements. Whether you're replacing a bowl, purchasing a new downstem, or upgrading your setup, understanding joint sizes can help prevent ordering the wrong parts.
Understanding Joint Sizes
The most common ROOR® joint sizes include:
- 14.5mm
- 18.8mm
Male vs Female Joints
A male joint inserts into a female joint. Determining which style your piece uses is the first step in finding compatible accessories.
How to Measure a Downstem
- Remove the downstem from the piece.
- Measure from the bottom of the ground joint to the tip of the tube.
- Compare your measurement to the replacement specification.
How to Measure a Bowl
Identify the joint size first, then determine whether you need a male or female connection.
