Bucket Spacers

stacks of 5 gallon bucketsObviously the best way to store a bunch of 5 gallon buckets is to stack them neatly into bucket skyscrapers, like I’ve done here. I often build stacks of 10 or more buckets at a time.

Unfortunately when you stack more than a few buckets together, they combined weight of all those buckets compresses all the air out. This causes the vacuum that makes tugging them apart difficult.

One solution is to drill holes in the bottom of every bucket but then your buckets are become less useful.

Or you could just yank them apart every time using our unstick stuck buckets technique.

We found the Bucket Spacer idea on Pinterest. Slip a scrap piece of 2×4 between each bucket to prevent the vacuum in the first place with some scrap 2x4s. It’s and easy, cheap and elegant solution.

5 Gallon Bucket Dimensions

dimensions 5 gallon bucketThe most common questions I get asked about 5 gallon buckets are regarding their dimensions. I’m hesitant to answer questions on the dimensions of a 5 gallon bucket because it will vary between models, sometimes significantly.

So this article is an attempt to catalog the most popular 5 gallon buckets in use today, along with their weights, measurements, capacities and anything else relevant. I’ll also be linking to the manufacturers’ specification sheets where available so you can delve much deeper into bucket statistics. Continue reading

Types of Food Grade Plastic

This page will cover three different types of food grade plastics you are likely to come across in your plastic bucket journeys. There are other food grade plastics such as PET, PCP and the increasingly unpopular BPA not covered here, but they are usually not used to make buckets.

HDPE or High Density Poly Ethelene plastic has an amazing temperature range, and is considered safe for short periods up to 248°F (120°C) or for long periods up to 230°F (110°C.) Since boiling water never gets above 100°C, this means that anything boiling and below is safe for a food grade bucket.

It’s important to make sure the bucket you are storing hot liquids in is HDPE however, as a similar plastic, low density polyethelene, actually has a temperature limit of 176°F (80°C) which is well below boiling. To see which type of plastic you are working with, just check the small recycling symbol usually found on the bottom of the bucket. HDPE is the one you want to see!

Sometimes I find a polypropelene or PP plastic bucket used for food, usually smaller containers that are thinner and less rigid than standard five gallon buckets. Polypropene has the highest temperature rating of all, but is considered a low to moderate health hazard by the Environmental Working Group.
High Density Polyethelyne

  • 230°F  temperature limit
  • Usually food grade
  • Recycle symbol 2
  • Example: Most five gallon buckets

 

 

Low Density Polyethelyne

  • 176°F temperature limit
  • Usually food grade
  • Recycle symbol 4
  • Example: 18 gallon rubbermaid totes

 

 

Polypropelene

  • 275°F temperature limit
  • Usually food grade
  • Recycle symbol 5
  • Can release a mild or moderate toxin
  • Example: Yogurt containers
