ROOR Germany Downstem Open-Ended (Not Diffused) 19mm - Lengths 9.0cm-17.5cm

ROOR Germany Downstem Open-Ended (Not Diffused) 19mm - Lengths 9.0cm-17.5cm

Stem Measurement Details (photo attached to show measurement may show a different downstem for reference purposes) - Brand-By-Brand:
From our experience, the STANDARD method of measuring Ground Joint Stem length is generally to measure the amount of glass that's below the 'joint' to measure how deeply into the bong the stem goes, beyond that joint... SO, generally they are measured from the bottom of the ground glass (frosted) joint to the absolute bottom of the stem. Unfortunately this rule is complicated by some brands that do things a little differently, so the following is our understanding of the stem measurement protocols of our most popular glass brands. Please also note that, as with all blown-glass items, there is always a little variation from one stem, and one measurement, to the next - so please allow for a slight variation in measurement and don't expect the numbers to be EXACT. If you have any uncertainty regarding measurement please don't hesitate to contact us at for clarification or help of any kind!

How each glass company measures their Glass-On-Glass (a.k.a. Ground-Glass) Joint Down-Stems:
Cheech: Measured from bottom of ground-glass joint to bottom tip.
GEAR: Measured from tip to tip (overall length) - therefore, about 2.5cm / 1" higher a number than the standard method would give.
HOSS: Measured from TOP of ground-glass joint to bottom tip.
Illadelph: One option - fits both beakers and straights (and Micro-Mini fits Micro-Minis).
Infyniti: Measured from top of ground-glass joint to bottom tip.
Nice: Measured from bottom of ground-glass joint to bottom tip.
NoName: Measured from bottom of ground-glass joint to bottom tip.
OG: Measured from bottom of ground-glass joint to bottom tip.
Preemo: Measured from bottom of ground-glass joint to bottom tip.
ROOR: Measured from TOP of ground-glass joint to bottom tip.

With a Roor pipe, you see smoking as a culture, not consumption. That is our responsibility, our motivation and our task. As a four-time winner of the High Times Cup, we see the awards at international trade fairs as a motivation to remain true to our philosophy. Over the years, RooR has rightly attracted tons of celebrity fans and friends: B-Real, System of a Down, Howard Marks and many more.

RooR glass pipes enable a premium smoking experience. With us, the highest demands on workmanship and material meet design and decades of experience in handicrafts. The precise processing of exclusively high-quality laboratory glass is our product promise - this is how we guarantee first-class smoking pleasure.

Unique to RooR are the numerous options to get to know the individual smoking behavior, to optimize it and ultimately to individualize it with regard to taste, intensity and aesthetics. Thanks to the modular system, our pipes adapt to an experimental smoke sensation over the years.

We are "the one and only"! It's not for nothing that people have been trying to copy us for years or to hold a candle to our wealth of creative ideas. ROOR has been valued for consistent quality for decades and is more than a brand - we are a community!

The feedback from our customers around the world guarantees the continuous development of our product lines. Numerous innovations - such as the anti-roll system, ice notches or the diffuser - have always ensured RooR's pioneering role in the market for sophisticated smoking products.

As early as the mid-1990s, the artisan Martin Birzle devoted himself to the manufacture of glass pipes. His expertise in the glassblowing trade is combined with the claim not to create mass-produced goods, but works of art. His philosophy: Highest quality and best functionality with an individual and appealing design.

Do you want a special one-off piece that is tailored to your optical and functional wishes? Almost all of our series pipes can be individually adapted and we are happy to take on the challenge, as far as possible, even with special extra requests.
