First Installation of J-J Hooks MASH TL3 Bolt-Down Barrier System

Easi-Set Worldwide, a Subsidiary of Smith-Midland Corporation, Is Proud to Announce the First Project Using the Newly Introduced J-J Hooks MASH TL3 Barrier

MIDLAND, VA--(Marketwired - May 20, 2013) - On March 18th, 2013, Shea Concrete Products of Wilmington, MA, a licensee of Easi-Set Worldwide (subsidiary of Smith-Midland Corporation) (OTCQB: SMID) completed delivery of the new J-J Hooks MASH TL3 bolt-down barriers with the Easi-Set/Hilti anchoring system to the Larz Anderson Memorial Bridge project in Cambridge. The bridge, listed on both State and National Historic Registers, was built during the late 1800s and is a vital transportation link connecting the cities of Cambridge and Boston and is the primary connection between two Harvard University campuses.

The Massachusetts Department of Transportation is carrying out the rehabilitation project as part of the Commonwealth's $3 billion Accelerated Bridge Program, which is expediting the rehabilitation or replacement of bridges with serious deficiencies by 2016.

The MASH barriers represent an expansion of the successful J-J Hooks self-aligning connection system used in "free-standing" installations for over two decades. "They are unique because they can be bolted to bridge decks or pinned to highways, meeting the new FHWA MASH TL3 requirements," said Greg Stratis, Shea Concrete Products Manager.

Shea Concrete has been providing barriers to the Massachusetts market for over 20 years. With the addition of the J-J Hooks MASH TL3, Shea Concrete has become one of only two certified manufacturers that can supply bolt-down barriers to MassDOT projects.

"I think (Shea Concrete's Certification) is a great thing for the industry," Matt Casey, Project Superintendent said. "Shea Concrete provides a great product. Project labor wise it installs three times quicker."

Easi-Set Worldwide designed and MASH-tested the bolt-down barriers and partnered with Hilti to offer a proprietary anchor system that requires only two bolts per 12 foot section. This allows fast installation and easy removal of barriers without flame cutting bolts or damage to the bridge deck. Removal only requires taking the locked bolts out of an adhesive embedded Hilti threaded anchor and filling the small recessed void with a concrete grout. The J-J Hooks MASH TL3 barriers are configured and tested to allow for both bolt-down and pin-down applications with lengths of 10, 12, 20 and 30 feet.

Easi-Set Worldwide is the industry's largest licensor of precast concrete products and a wholly-owned subsidiary of publicly-traded Smith-Midland Corporation (OTCQB: SMID). For more information on J-J Hooks MASH TL3, Easi-Set, and its product lines can be found at and
