PRODUCT DESCRIPTION 

le' New Hardware or (' Modification to 

• Significant Modification Existing Hardware 

The Sentry II Water Cable Barrier is a longitudinal barrier designed to contain, redirect, and shield vehicles from 

roadside obstacles while providing positive protection and separation between the traveling public and the 

personnel in the work zone. The Sentry II was designed for TL-3 (62.1 mph/ 100 km/ hr) application. The barrier 

is also designed for TL-2 (43.5 mph/70 km/ hr) and TL­1 (31 .1 mph/SO km/ hr) applications. The Sentry II is a freestanding system that does not require anchoring to the road surface and can be used on concrete, asphalt, 

gravel, and dirt surfaces. The surfaces used for testing were concrete and dirt. The system consists of individual 

water filled plastic modules that are connected to adjacent modules creating a continuous barrier wall of 

unlimited maximum length with minimum Length Of Need (LON) of 15 connected modules. An empty 

module weighs approx. 215 lbs. (97.5 kg) and 2, 150 lbs. (975.2 kg) when filled with water. Each module is 

designed to utilize an optional drive by float lid for visual water level inspection. The modules are 

manufactured from polyethylene that is UV stabilized. Orange and white barrier modules were the as tested 

colors, and the product may be produced in other colors as needed. Adjoining modules can rotate up to 15 

degrees at the connection point, allowing the barrier wall to contour to varying road curvature. Individual 

modules have overall dimensions of 75.6 in (1.9 m) long, pin to pin X 22.5 in (0.57 m) wide X 45.8 in (1.2 m) tall. 

Each module is designed with 11 connecting knuckles, 5 on one end, and 6 on the opposite end. Within the 

top four knuckles on each end is series of four permanently molded in corrosion resistant steel cables. The 

cables run longitudinally along each module and create an internal cable barrier. When the modules are 

installed together, the knuckles concentric vertical through holes align with adjacent modules knuckles 

concentric vertical through holes. This hole alignment allows for a steel pin to be inserted through all eleven 

knuckles creating a positive connection between modules, and a continuous internal cable barrier within the 

connected modules. Upon impact the plastic modules rupture, dispersing the contained water, 

simultaneously the impacting vehicle engages and tightens the internal molded-in cable barrier. 

CRASH TESTING 

By signature below, the Engineer affiliated with the testing laboratory, agrees in support of this submission that 

all of the critical and relevant crash tests for this device listed above were conducted to meet the MASH test 

criteria. The Engineer has determined that no other crash tests are necessary to determine the device meets 

the MASH criteria.

The Sentry II Water Cable Barrier was angled 

2s 0 from the direction of the impacting 

vehicle. The side angle impact examines 

the barrier's ability to contain, re-direct, or 

bring the vehicle to a controlled stop. The 

vehicle should not penetrate the installation 

while controlled lateral deflection of the test 

article is acceptable. The test was 

conducted using a commercially available 

2013 Kia Rio 4-door sedan with a test 

inertial mass of 2,461.4 lbs. (1 ,116.5 kg). The 

veh icle was in good condition, was free of 

major body damage, and was not missing 

any structural components. The bumpers 

were standard equipment and were not 

modified for this test. Based on CarFax 

reporting there was no recorded history of 

major accidents, was not a salvaged titled 

vehicle, not involved in flooding, or fire. The 

test vehicle impacted the barrier at a 

velocity of 62.37 mph (100.37 km/ hr) and at 

an impact angle of 25.1°. The as tested 

barrier consisted of 25 water filled modules 

pinned together measuring 157.8 ft. (48.1

INTENDED USE 


The Sentry II Water Cable Barrier is a longitudinal barrier designed to contain, redirect, and 

shield vehicles from roadside obstacles while providing positive protection and separation 

between the traveling public and the personnel in the work zone. The Sentry II was designed 

for TL-3 (62.l mph/ 100 km/hr) application. The barrier is also designed for TL-2 (43.5 mph/70 

km/hr) and TL- I (31 . l mph/50 km/hr) applications. The Sentry II is a free-standing system that 

does not require anchoring to the road surface and can be used on concrete , asphalt, gravel, and 

dirt surfaces. The surfaces used for testing were concrete and dirt . The system consists of 

individual water filled plastic modules that are connected to adjacent module s creating a 

continuous batTier wall of unlimited maximum length with minimum Length Of Need (LO ) of 

15 connected modules. An empty module weighs approx . 215 lbs. (97 .5 kg) and 2, 150 lbs. 

(975.2 kg) when filled with water. Each module is designed to utilize an optional drive by float 

lid for visual water level inspection. The modules are manufactured from polyethylene that is 

UV stabilized. Orange and white barrier modules were the as tested colors, and the product 

may be produced in other colors as needed. Adjoining modules can rotate up to 15 degrees at 

the connection point, allowing the batTier wall to contour to varying road curvature . Indivi<lual 

modules have overall dimensions of 75 .6 in (1.9 m) long, pin to pin X 22.5 in (0 .57 m) wide X 

45.8 in ( 1.2 m) tall. Each module is designed with 11 connecting knuckles, 5 on one end, and 6 

on the opposite end. Within the top four knuckles on each end is series of four permanently 

molded in corrosion resistant steel cables. The cables run longitudinally along each module and 

create an internal cable barrier. When the modules are installed together, the knuckles 

concentric vertical through holes align with adjacent modules knuckles concentric vertical 

through holes. This hole alignment allows for a steel pin to be inserted through all eleven 

knuckles creating a positive connection between modules, and a continuous internal cable 

barrier within the connected modules. Upon impact the plastic modules rupture, dispersing the 

contained water, simultaneously the impacting vehicle engages and tightens the internal 

molded-in cable barrier.
