These are the smallest heating units on the market and not to mention the lightest, a mere 75 lbs. The quality of heat out-performs all hand torches and not to mention eliminates the need for a worker to operate a torch during the heating process.
The unit not only heats 1×4 foot area, but can be pinned to a second 1×4 heater to operate as a 1×8 and a 2×4 unit. The switch between operating modes is made easy and tool-free, by changing wheel bracket positions. The 1×4 Heaters are exceptionally good for smoothing joints to a seamless patch, fixing drainage problems, erasing tire indentations and printing stamped asphalt borders.
