Revision E (Dated 11/26/12) 1
Limitations and Warnings
TrafFix Devices Inc., in compliance with the National Cooperative Research Highway Program 350
(NCHRP350) recommended procedures for safety performance evaluation of highway features,
contracted the services of an approved ISO certified independent test facility, to conduct crash tests,
report findings, and provide complete testing evaluation reports.
The SLED End Treatment System is accepted by the Federal Highway Administration (FHWA) for
use on the National Highway System. TL-3 and TL-2 meet the NCHRP 350 requirements, using the
test impact vehicles that range from light weight cars of approximately 820 kg (1800 lbs), to full-size
pick up trucks of approximately 2000 kg (4400 lbs).
A series of inline, offset, side and angle impacts at a designated speed of 100 kph (62.1 mph) were
conducted to verify the SLED’s impact performance. All Occupant Risk Values were deemed a
PASS per NCHRP 350 specifications.
The SLED End Treatment System is designed to be installed and maintained in accordance with the
recommendations and guidelines of the governing state and FHWA.
After an impact, damaged components should be removed and replaced with new components.

Revision E (Dated 11/26/12) 3
System Overview
The SLED End Treatment System is a gating, non-redirective crash cushion designed to shield the
end of permanent and portable barriers made of concrete, steel, or plastic. The SLED End Treatment
System is designed for uni– and bi-directional traffic flow applications (or on pp. 47-48).
Crash Performance
The SLED End Treatment Modules are yellow in color. The NCHRP 350 Test Level 3 (TL-3)
System has an overall length of 26 ft (7.92m) long and is 1.875 ft (0.57m) wide. The NCHRP 350
Test Level 2 (TL-2) System has an overall length of 18.9375 ft (5.77m) long and is 1.875 ft (0.57m)
wide. Each Module has overall dimensions of approximately 6.3 ft (1.93m) x 1.875 ft (0.57m) x 3.8
ft (1.16m) and weighs approximately 160 lbs empty and 2000 lbs full.

Product Overview and Function
The SLED End Treatment System is a water filled gating non-redirective crash cushion designed to
shield permanent and portable barriers. The TL-3 SLED End Treatment System consists of three water
filled and one empty plastic modules to produce the desired energy attenuation characteristics to
decelerate an impacting vehicle to meet TL-3 crashworthy requirements of Report NCHRP 350.
Attached to the front empty module is the patented Containment Impact Sled (CIS) which collects the
ruptured debris in front of the impacting vehicle..
Additional Features:
NCHRP 350 TL-3 and TL-2 Tested – Accepted for use on the National Highway System as a
TL-3, Crash Cushion, CC-114 and a TL-2, Crash Cushion, CC-117.
Overall TL-3 array length is 26 ft (7.92m) and TL-2 array length is 18.9375 ft (5.77m) long.
 Acceptable for Permanent and Portable installations.
 Attaches to various barrier shapes made of concrete, steel, or plastic.
All metal components are domestic sourced steel in accordance with Buy America requirements.
Does not require any external steel for module assembly.
Rotational molded plastic, modules are manufactured from specially formed material
designed to be durable when handled and attenuate when impacted.
 Module sections up to ½” (14 mm) thick reduce nuisance hit damage and the potential for
vandalism.
 Designed for use in uni– or bi-directional traffic flow applications.

SLED Identification and Orientation
Figure 2 (or on pg. 38) identifies the TL-2 SLED End Treatment Systems front and rear orientation
for installation. Figure 3 (or on pg. 39) identifies the TL-3 SLED End Treatment Systems front and
rear orientation for installation. The Containment Impact Sled orients the front. Module #1 attached
to the shielded barrier orients to the rear. This same configuration can be used in uni- or
bi-directional traffic flow applications.

Product Components and General Specifications
Module Specifications
All SLED End Treatment System
Modules are yellow in color and have an out-
er shell made from energy attenuating plas-
tic. The modules will collapse and
rupture when impacted and disperse the
contained water. The modules will not crack
or corrode when left on the job site or stored
for long periods of time.
Overall Dimensions:
Width: 22½” [571 mm]
Height: 42-11/16” [1084 mm]
Length 75-3/4” [1924 mm] pin to pin
Weight:
Empty Weight: 160 lbs. [73 kg]
Filled Weight: 2000 lbs. [907 kg]
Fill Capacity:
Volume: 220 Gal [832 L]
Each module contains an eight inch
diameter water fill-hole located on the
top surface of each module section. This
large diameter opening allows for easy
access for water filling using a large
diameter hose from a water tanker truck.
Each module comes with a twist lock
lid to cover the fill hole opening when
the water filling process is complete. A
water level indicator is designed into the twist lock lid. Figure 6 (or on pp 7 and 52) .
For draining, a central drain hole is located at the bottom of each module. Each drain hole contains
molded-in Buttress threads. The drain plug requires 1-1/2 turns to seal the plug preventing any water
leaks. The molded-in Buttress threads eliminate the possibility of cross threading compared to standard
threads used in a spin welded insert. Cracked spin welded inserts may require repair and are typically
not reliable, leading to water leaks. The SLED Modules, with molded in Buttress threads, eliminates
both issues of cross threading and insert repair.
Two forklift pockets (slots) are designed into the modules, located at grade level, which can be used to
insert forklift blades for moving the filled or unfilled SLED Modules sections as needed. The molded-
in steel cables ARE NOT be to be used for lifting the modules. Only the two forklift pockets
(slots) should be used to lift the modules as identified in Figures 4 and 5 (or on pp. 40 and 41).

Containment Impact Sled
The Containment Impact Sled (CIS) is attached to the front empty module Figure 7 (or on pg 42). The
steel CIS is hot dipped
galvanized to minimize the
affects of corrosion. Upon
impact, the CIS slides rearward
collecting the ruptured mod-
ules.

The CIS is tube frame designed with a curved front cap and a flat steel bottom. The CIS is pinned onto
empty No-Fill Module with a vertical T-pin that drops through a series of the concentric holes in the
