The strutter slides into strut because itâs so short and get under the strut lip. Perfect for the Electrician that is securing heavy loads and needs to use 1/2â³. The Strutter Socket can be turned sideways, slide into the strut, then slid over to the 1/2â³ bolt and tightened up. Fast and easy for electricians that spend a lot of time securing strut in industrial. Before, you could only install the 3/8â³ bolt, but now, for heavy loads and maximum strength, use The Strutter Socket. PAT. NO. 179.392:29/578,226
