Arlington Industries 129 – Frequently Asked Questions

1) Will the Arlington 129 entrance cap fit 2-1/2 inch rigid mast?
Yes. The Arlington 129 is a reducer cap: it slips onto 2-1/2 inch mast and reduces down to a 2 inch cap opening. If your mast is a straight 2 inch, you want a straight 2 inch entrance cap instead, not this reducer.
2) How many service entrance conductors can the Arlington 129 mast cap take, and what size holes?
The cap is drilled for six conductors: one 0.53 inch hole, two 0.75 inch holes and three 1.00 inch holes. That mix lets you bring in a large pair of ungrounded conductors through the 1.00 inch openings and a smaller neutral or ground through the 0.53 inch, without drilling anything on site.
3) How much clearance do I need above the roof or gutter to install the Arlington 129 cap?
Allow for a fitting measuring 5.236 inches in height and 6.506 inches across. Add that to your mast height when you are laying out drip loop and clearance above the roofline, because the cap sits on top of the mast, not inside it.
4) What is the difference between a mast reducer cap and a regular entrance cap?
A regular entrance cap matches the mast it sits on, one size in and the same size out. A reducer like the 129 steps a 2-1/2 inch mast down to a 2 inch cap, which is what you use when the mast was upsized for strength on a long riser but the conductor count does not need a full 2-1/2 inch head. Match the mast size first, then confirm the conductor holes suit your service.
5) Will an aluminum entrance cap hold up on a coastal or exposed mast?
The 129 body is aluminum with a silver finish, which is the usual choice for outdoor weatherhead service because it will not rust the way a plated steel fitting does. It is a weatherproof cap for overhead service drops, so exposure is the normal duty for it.
6) Can I order one Arlington 129 mast cap or does it come in a case?
It is sold as a single piece, model 129, at 0.980 lbs each. The manufacturer's standard carton is 6 pieces, so a shop stocking a service truck can take a case or a one-off replacement can be bought on its own.
