HOAC® system frame
— One for all

Developed by us, the frame is versatile – for stages, turntables, grandstands, stage design, stage wagons, orchestra stages and much more. Thanks to our system concept, you can exchange the frames flexibly – today a stage, tomorrow a grandstand. In doing so, we focus entirely on your needs. With our production in Germany, we can customise the design, dimensions and load for you. In addition, we continue to develop our products to meet your needs – even simpler, even better.

Stage construction so simple — with HOAC® link block

The heart of our HOAC® frame is the link block. The frames can be connected to each other force-locked and form-fitted in no time at all — without any tools. The firmly welded frames are mobile and can be assembled and disassembled at any time. You think that sounds exciting? So do we! But even more exciting is the further development of the system and the joy of our customers about their work being made easier.

HOAC® modular frame system
For maximum compatibility 

In addition to our standard system frames in 105 mm, 140 mm and 173 mm construction heights, there are other frame profiles for different applications. Flip2Play for quick and easy stage construction – also known as Klapppraktikabel. TackIt is the system for stage set construction and much more. The highlight of our HOAC® system is its compatibility and the resulting sustainability. You can connect any HOAC® profile to each other with our link block.

Covering and locking
Simple, is simply great

With our cover plates, you can have a 10-m turntable covered in under 10 minutes. It is fascinating how quickly stage construction can be done. Simply place the cover plate on the frame and with a twisting motion lock the cover plate firmly onto the frame via the mounted panel lock.

Twist2Lock easy connection

HOAC® Grandstand railing
Hook it in and you’re done!

With our snapper, the grandstand railing can be attached to any HOAC® system frame. The railing is hooked in and is then firmly attached to the frame. It’s the little things that make us special.

Attach any leg with the angular plug-in leg holder

All feet, whether telescopic, height-adjustable, angular or round, are simply attached to the frame with the angular plug-in foot holder.

The most efficient way to store frames

An extra storage cart for system frames? Not with us! With our wheel holder you can turn every HOAC® system frame into a storage cart.

The backloaded link block – more flexibility is not possible.

You want to spontaneously remove an element in the middle of your stage? With our Backloaded link block – nothing could be easier. The special feature is that you can remove the frames directly in the middle and do not have to start from the side first. So you can quickly move the stage shaft for the performers during the change of scenery.
