HEAVY 16 1G/2.5G Wrench (4L/10L)

A Lightweight Wrench for HEAVY 16's Smaller Jugs

A cap that's on tight, or slick from a splash of concentrate, can be hard to twist off by hand, and a metal tool risks marring the plastic threads on a smaller jug. HEAVY 16's plastic wrench is sized specifically for its 1 gallon and 2.5 gallon jugs, giving growers a purpose-built grip instead of improvising.

Its lightweight plastic build makes it a simple, low-cost tool for the smaller sizes in the HEAVY 16 lineup, rather than the heavier aluminum wrenches used on the bulk drums.

• Fits 1 and 2.5 gallon jugs — sized for HEAVY 16's 4 liter and 10 liter containers

Who Should Use This Wrench

Growers working with HEAVY 16's 1 gallon or 2.5 gallon jugs who want an easier way to open a tight or slick cap will use this wrench.

About HEAVY 16

HEAVY 16 was formulated by Bryce Patterson, a Cal Poly-trained horticulturist based in Signal Hill, California, around three principles: high-grade raw ingredients, complex chemistry that simplifies application, and micro-batch blending for consistency. Alongside its base nutrients and additives, HEAVY 16 also sells the container hardware — spigots, caps, wrenches, and a transfer pump — that growers need to draw from and open its bulk container sizes.

Frequently Asked Questions

What size containers does this wrench fit?

This wrench is designed for HEAVY 16's 1 gallon and 2.5 gallon jugs (4 liter and 10 liter sizes). It is not sized for the 6, 15, or 55 gallon containers, which use HEAVY 16's aluminum bung wrenches instead.

What material is this wrench made of?

It's made of plastic, which keeps it lightweight and avoids marring the plastic threads on a smaller jug cap. This differs from the aluminum wrenches HEAVY 16 sells for its larger bulk drums.

How do I use this wrench on a tight cap?

Fit the wrench over the jug's cap and turn to break it loose if it's stuck or slippery from spilled concentrate. It's built for occasional use on a cap that won't turn easily by hand.

Is this wrench easy to use?

Yes, its lightweight plastic design makes it simple to grip and turn on smaller containers without much effort. It's a low-cost accessory worth keeping on hand alongside a HEAVY 16 jug setup.
