Having had a difficult time trying to get a company using spark erosion to make a few one-off samples, I decided to visit a local engineering company and they eventually made me 20 blanks. I regularly use their holesaws, ¼” drive bit sets and HSS drills, so I wanted to set the standard high in terms of quality and looks. After having a 3D version printed, I realised the user could not locate it easily because the cross was not visible enough. I chose Armeg because I like the products, I use their Holesaws, ¼” drive bit sets, HSS drills and like the quality.

The most common situation for me to use the gutter bolts/roof bolts are in commercial or industrial situations, where cable management trays are being used above suspended ceilings. To make driving easier, the tools are magnetic to maximise the connection with the fastener, for secure holding and hassle-free start-ups. The technical storage or access is strictly necessary for the legitimate purpose of enabling the use of a specific service explicitly requested by the subscriber or user, or for the sole purpose of carrying out the transmission of a communication over an electronic communications network. The majority of electrical work has been commercial and industrial installations, but I do quite a lot of domestic work too!

When working at height, which is often the case with cable management, you need things to be much easier.

I do this daily on industrial contracts and sometimes on commercial jobs in the initial stages of the installation. After having a 3D version printed, I realised the user couldn’t locate it easily because the cross was not visible enough.

The patented product was invented and designed by a professional electrician, John Mijalski, after snapping off a flat head screwdriver during a roofing bolt installation.
