Hole Formers

Strike Products' hole former line is made with the "Precast Friendly" material called polyethylene. We have found over the years that HDPE (Polyethylene) is an excellent material for holding up to the power of concrete. It's non-stick surface features, enables it to strip with ease.

Take some time and check out each page of our hole former line. We have taken the standard hole former to a new level with the Precision Hole former. We have also started making High Tapered Blockouts as well as Dog House Blockouts. If you're looking at creating lift hole, we also make a Poly Lift Hole Formers.

Attachment Devices
Hole Plug •  Magnet Plate • Lever Magnet

The polyethylene hole formers are equipped, (unless noted), with a 8" diameter center hole which is used for various different attachment devices. We have the hole plug which allows you to bolt the hole former to your forms. We also manufacture a magnet plate which is used with our round magnet for hole formers 11" and greater.  Our lever magnet is designed to fit inside the standard 8" center hole on all hole formers 11" and greater.  Hole formers 10" and down have a 2.75" hole to accommodate our round magnet without needing our magnet plate.

Along with these attaching devices you can also do it the old fashion way and just tie wire it in. With this hole former being so light and easy to handle, there are several ways for keeping our hole formers in place.
