When it comes to choosing the right size beer shank, there are a few factors to consider. The most common size is the 4 1/8″ shank, and this is often the default choice for many home brewers and bar owners. One of the main reasons for this is that it is long enough to fit through the door of most refrigerators, making it convenient for installation.
Additionally, having a little extra shank inside the kegerator or keezer can be beneficial. This extra length helps to keep the shank colder, ensuring that your beer does not come into contact with a warm shank. When beer passes through a warm shank, it can cause unnecessary foam, affecting the overall quality of your pour. By having a longer shank inside the cooling unit, you can help maintain a colder temperature and reduce the risk of foam.
While the 4 1/8″ shank is commonly used, it is worth noting that there are other sizes available on the market. These sizes can vary depending on the specific requirements of your kegerator or keezer setup. It is essential to measure the thickness of your cooling unit's wall and take into account any additional insulation, if present.
If you find that the default 4 1/8″ shank is not suitable for your specific setup, you may need to consider a longer shank. This is particularly true if you have a thicker wall or added insulation in your cooling unit. Measuring the depth of your cooling unit and subtracting the thickness of the wall will give you a better idea of the shank length you require.
In some cases, you may even need to use a custom-sized shank to ensure a proper fit. This can be more challenging to find, but specialty retailers or online suppliers may offer custom shanks or adapters that can accommodate your specific needs.
It is also essential to consider the type of faucet and other accessories you are using with your shank. Different faucets may require specific shank sizes or adapters to ensure a proper fit. Be sure to check the manufacturer's recommendations or consult with a knowledgeable supplier to ensure compatibility between your shank, faucet, and other components.
In my personal experience as a brewer, I have encountered situations where the default 4 1/8″ shank was not sufficient. For example, when installing a kegerator inside a custom-built cabinet, the wall thickness was greater than average, requiring a longer shank to reach the faucet properly. By measuring the depth of the cabinet and factoring in the wall thickness, I was able to determine the correct shank size needed for a successful installation.
To summarize, the size of the beer shank you need will depend on the specific requirements of your kegerator or keezer setup. While the 4 1/8″ shank is commonly used due to its versatility, it is essential to measure your cooling unit's wall thickness and consider any additional insulation. If necessary, longer or custom-sized shanks may be required to ensure a proper fit. Be sure to also consider the compatibility of your shank with faucets and other accessories.
