Step 3 · Trim the Insulation Covers
Lay out the shield components on a flat, stable work surface, preferably a cutting mat to protect the underlying surface. Transfer the measurements from your notepad to the corresponding shield pieces. Most pre-molded kits are made of a semi-rigid vinyl or PVC that can be cut easily. Use a sharp utility knife with a new blade or a pair of heavy-duty scissors/shears to make clean, straight cuts. Follow any score lines provided on the pieces. For your safety, always cut away from your body. Re-measure the cut pieces to confirm they match your required dimensions.
