Here you go. I feel safer if you can confirm. Mine are broke, hard to confirm.

I'm afraid it's not easy to reliably read dimensions of measuring tape from a photo. The depth can be thought of as the 'heel-to-toe' measurement. For the Series 351, the depth of the shoe is 1"; for the Series 390, the shoe is 1-1/8" deep. Place the measuring tape just below and perpendicular to where the metal channel ends. Any reading slightly greater than 1" suggests you have a Series 390; sometimes the shoes wear down over time. Let us know if you have any other quesitons. |
