Review on Grommets Petal Shaped Management Protection Cabinet by Robert Espinoza

I bought these grommets to protect XLR cables that would otherwise run through unprotected holes drilled in the metal case. The grommets fit the 1-3/8 holes perfectly, but the vinyl pins in the center of the grommets are so stiff that it was difficult to insert the cables and I was concerned that the edges of the pins would cut into the cable jacket . I threw away those vinyl bushings and ordered rubber bushings instead.
