--> KR-List message posted by: <[EMAIL PROTECTED]> Passing wire and cables through the fire wall can be accomplished by using the appropriate sized electrical nipple. Let us say that you have to put a marine push/pull cable of 3/8 " diameter through the fire wall. Get a 2" or 3" nipple through which the cable fits snugly. Use a hacksaw to cut out the upper half of one end for about 3/4" from let us say the right hand end. Use a nut on both sides of the firewall to retain the nipple or weld a circular plate onto the nipple and by means of 3 screw mount it through a hole in the firewall.Push the cable (or wire) through and anchor it to the nipple with a 1/4" stainless steel adjustable clamp which goes over the top of the cable and under the buttom of the uncut portion of the nipple. The fixture can be completely sealed with high temperature silicone if desired. You have only to choose the size of the nipple to suit your cable/wire situation. Electrical nipples are much lighter than iron plumbing nipples. Harold Woods Orillia,ON.Canada. [EMAIL PROTECTED]
