Concrete Dobies
The term “Dobies” has become the trade name for concrete rebar supports over these last fifty years.
They come with, or without tie wire inserted in the concrete brick. We manufacture these in regular strength, 4000 PSI mix design, or higher strength for specific jobs.
Form Supports & Spreaders
These are typically used by general contractors in bridge decks and other concrete forming applications. They come in longer sizes such as 24” or 48”, and depending on length, will be reinforced with rebar. Form supports are also stocked in 5”, 5 ½”, 6”, and many other heights.
Plastic Spacers & Wheels
We first designed the On Grade Square Chair application almost thirty years ago under a different name. Now we have three plastic chair types: Square Chair, Tilt Chair, and Hi Chairs.
Slab Bolster
We spared no expense on the new bolster, and have re-engineered the buckles.
Available in both boxes or pre-assembled in 10’ lengths, we have had incredible success with the new and improved bolster. Currently, we do not manufacture a lightweight-use bolster, but have chosen to provide a super strong slab bolster to meet the demands of the toughest commercial projects. Available with or without staple down legs.

The Do’s and Don’ts of Tying Rebar
At a glance, the process of tying rebar may look easy. However, the reality is that is it quite a lengthy and complicated process. While it isn’t exactly rocket science, there are still a lot of things one needs to take into consideration when tying rebar.
