Crete-Sleeve®: The #1 Brand in Plastic Hole Forms Since 1965

For over 50 years, Crete-Sleeve® has been producing the highest quality plastic hole forms for the construction industry. Crete-Sleeve® Plastic Hole Forms are used by electricians, plumbers, HVAC and concrete providers to create a hole in a concrete wall or floor so they can run their conduit and piping from one wall or floor to the next. Just attach the Crete-Sleeve® to the form, pour the concrete and after the concrete has cured, remove the sleeve leaving a perfectly round hole saving you time and money!


Why Choose Us?

At Crete-Sleeve®, we do one thing and one thing only: manufacture, service, and sell the best performing plastic hole forms on the market.

Highest Quality Product

Crete-Sleeve® Plastic Hole Forms are:

  • Manufactured in-house to ensure quality control.
  • Manufactured using green composites for purity, guaranteeing a stronger and more durable product.
  • Reusable with a smooth surface that will not adhere to the concrete.
  • Lightweight, have no sharp edges, and are easy to handle. Our plastic hole forms outperform metal every time.
  • Able to be telescoped or cut for any slab thickness.
  • Available in 9 sizes to meet all of your needs.

Saves Time and Money

Cutting your own metal piping, plastic tubing or drilling your own holes is time consuming and labor intensive. Drilling doesn’t guarantee a smooth, round hole every time, and there is also the risk of cutting the rebar and reducing strength.

Crete-Sleeve® Plastic Hole Forms can be attached to a metal form with wire or a wood form using screws, nails or staples and are easily removed after the concrete has cured. They won’t chip, dent, or break, and leave a smooth, uniform hole every time – saving you labor, time, and money!
