GENERAL INFORMATION

DOUBLE

™

Shield Expansion Anchor

PRODUCT DESCRIPTION

The Double is a dual expansion machine bolt anchor particularly suited for materials of questionable

strength or consistence such as stone. It can be used in solid concrete, block, brick, and stone. Job

site tests are recommended when used in base materials of questionable strength or consistence.

FEATURE AND BENEFITS

• Performs in base material of questionable strength

• Internally threaded anchor for easy removablility and service work

• Corrosion resistant body

APPROVALS AND LISTINGS

• Tested in accordance with ASTM E488

• Federal GSA Speciﬁcation – Meets descriptive and proof

load requirements of CID A-A-1923A, Type 3

Installation Guidelines

Drill a hole into the base material to the minimum

depth required. The tolerances of the drill bit used

should meet the requirements of ANSI Standard

B212.15. Do not expand the anchor prior to

installation. Do not over drill the hole unless the

application calls for a subset anchor.

Insert anchor into the hole, threaded cone end first

until the outer sleeve is flush with the surface of the

base material.

Position fixture, then insert screw or bolt and tighten.

For maximum expansion, the upper cone should

protrude slightly before setting. The bolt must engage a

minimum of 2/3 of the anchor threads.
