Most screed and screed bar combinations produce irregular vibration along the length of the screed bar. Not only is the concrete exposed to highly variable levels of vibration but cream levels vary from spot to spot along the screed bar. The back-to-back triangular construction of the ScreeDemon™ bar is extremely rigid and minimizes variability in the transmission of vibration.
Most screeds bolt to their screed bars. Hardware threads are compromised by the concrete and assembling or removing the screed becomes such a problem that crews often don't disassemble for cleaning or transport. The ScreeDemon™ simply clamps to the specially designed bar. No holes to weaken the screed bar. No threads to complicate assembly/disassembly. The ScreeDemon goes together and comes apart in seconds.
