Royston Handy Cap

Corrosion Protection For
Exothermic Grounding Connections

What Is Royston Handy Cap?

The Royston Handy Cap is a prefabricated assembly' specifically' designed tor Cathodic Protection leads to pipes and tanks. When pressed by hand into positioned over the anode lead wire weld it forms a thick, high resistant electrical insulation seal over the weld, the end of I the lead wire and the surrounding area of
the pipe or tank.

Features

1) A top plastic sheet formed with an igloo shaped dome and entry tunnel for the lead wire.

2) A special elastomeric compoundin the plastic dome, which is firm enough to resist flow at all normallyencountered applications and operation tempatures, but soft enough to mold itself around and compleately cover the irregular welded profile.

3) On the either side of the dome are a double row of parallel, flexibilizing serrations to assist with conforming around small diameter pipe.

4) A base of Royston Tac- Coat, a black unbacked elastomeric tape with exceptional adhesive properties, for bonding firmly to the metal surface when used with Royston Roybond 747.

Usage
The Royston Handy Cap is easily applied and economical. They may be used on all anode lead wire and test wire weld areas.
Royston Handy Cap is especially useful for welds on mill coated pipe where only a small part of the cooting has been
removed to permit installation of the thermite grounding connections.

They are ideal for use in limited access situations, because they can be manipulated easily and applied at arm's length.

 How to use 

Step 1) Clean all mud, dirt, grease, oil and other
contaminants from the metal surface and
any part of the mill applied coating which
is to be covered. Apply a coat of Royston
Roybond 747 and allow to dry to a
non-glossy appearance, which will take
about 5 minutes, depending on humidity
and temperature.

Step 2) Remove the release paper from the
bottom of the Royston Handy Cap.
Bend the plastic sheet inward at the
serrations when applying to small
diameter pipe. Position and place the
Royston Handy Cap on the welded
area with the tunnel over the lead wire.

Step 3) Push the dome of the cap firmly into the
weld area. Now lin the lead wire away
from the pipe and squeeze the black rubber
compound completely around and
underneath the wire. Then push the lead
wire back down on the pipe and press the
elastomeric compound into firm contact
with the pipe over the entire area.
No further protection is necessary when
Royston Handy Cap covers the entire
exposed metal area. Uncovered areas
should be protected by applying tape or
mas~c, such as Royston Roskote Mastic.
When coating or wrapping the Royston
Handy Cap, remove the narrow strips of
plastic release film on the top of the cap.
This will assure maximum protection by
effecting a positive waterproof seal.
