Screen tubes are for use
in hollow CMU, hollow
brick and unreinforced
masonry applications.
Screen tubes are vital to the performance of adhesive
anchors in base materials that are hollow or contain voids,
such as hollow block and brick. The Simpson Strong-Tie
®
Opti-Mesh
®
screen tube provides the economical advantage
of a plastic screen tube while providing performance compa-
rable to steel screen tubes and better than competitive plastic
screen tubes.
MATERIAL: Plastic
Caution: Screen tubes are designed for a specific adhesive
type.EpoxyscreentubesmustbeusedwithSETorET-HP
formulations and acrylic screen tubes must be used with
AT adhesive. Do not use SET1.7KTA with screen tubes.
The integral cap
centers the rod
and displays
drill bit and rod
diameter.
Integral Cap: Serves to center and secure the
rod in the screen tube, while displaying impor-
tant information such as rod diameter, drill bit
diameter and the Simpson Strong-Tie
®
"≠" sign
for easy inspection after installation. The cap
also prevents adhesive from running out of the
front of the screen tube.
Flanges:Preventsthescreentubefromslipping
into over-drilled holes. Allows screen tube to
function in holes that are drilled too deep.
Open-Mesh Collar: This section of larger mesh
allows extra adhesive to flow out of the screen
tube behind the face shell of hollow block appli-
cations. The extra "collar" of adhesive increases
bearing area and results in higher load capacities
in hollow concrete block.
Color-Coded, Formula-Specific Mesh:
The screen tube mesh is sized to allow only the
right amount of adhesive to flow through
the screen tube to bond with the base material
while the balance remains in the screen to
bond the rod. The acrylic screen tube mesh is
white while the expoxy screen tube mesh is
black.

Epoxy (SET and ET-HP) Screen Tubes - Plastic
Load values for installations with SET are on page 30. Load values
forinstallationswithET-HPinunreinforcedmasonryareon
page 44. Not for use with SET1.7KTA.
The photo on the left shows the Opti-Mesh
®
screen tube installed
in a hollow CMU block. The extra collar of adhesive created by the
open-mesh collar results in increased bearing area and higher load
values. The typical screen tube shown on the right relies on the bond
between the relatively small amount of adhesive in contact with the
face shell of the block for its holding power.
