Through bolts (size and length as per utility specs) Washers and nuts Backer rod Silicone sealant Vinyl siding patch (if necessary)

Steps

1.

Locate Wall Studs

Use a stud finder or tap on the wall to locate the studs behind the vinyl siding.2.

Mark Attachment Points

Determine the locations for the through bolts and mark them on the vinyl siding.3.

Drill Pilot Holes

Drill small pilot holes through the marked locations and the vinyl siding into the wall studs.4.

Insert Backer Rod

Insert backer rod into the pilot holes to create a space for the sealant and prevent moisture penetration.5.

Install Through Bolts

Insert the through bolts through the backer rod and pilot holes. Place washers between the bolt heads and siding, and nuts on the other side. Tighten the nuts securely.6.

Seal Around Through Bolts

Apply silicone sealant around the through bolts and between the washers and siding to prevent water infiltration.7.

Replace Vinyl Siding Patch (Optional)

If the through bolts punctured the vinyl siding, cut a patch from a spare piece of siding and install it over the holes using sealant.

Tips: Use a socket wrench to ensure the nuts are tightened uniformly. Avoid overtightening the nuts to prevent damage to the vinyl siding. Consider using a bit of flashing around the bolts for added protection from water intrusion. If the wall structure is not strong enough to support the service mast, consider adding blocking or reinforcing the studs. Always follow the utility drawings and local building codes for proper installation and safety. Flag for review
