What Is Boxlok?
The Boxlok is a patented valve box alignment device designed to eliminate valve box shift during backfill. Engineered for use with cast iron valve boxes and 6" PVC pipe risers, Boxlok works with nearly all buried AWWA valves—without requiring valve disassembly. The Boxlok is made in the USA and meets BABA requirements.
No digging. No special tools. No wasted time.
How Boxlok Keeps Your Valve Box Centered
The Boxlok installs in seconds and holds the valve box centered around the valve operating nut. The non-load bearing design ensures that the valve itself is not supporting any weight or pressure, while preventing box shift or crooked boxes.
Why It Matters:
Valve box misalignment is one of the most common—and costly—issues faced during valve installations. When a valve box shifts during backfill or overtime with erosion, it can lead to inoperable valves, offset boxes and ultimately valve box reinstallation. These errors don’t just slow down inspections; they result in failed audits, costly rework, and added labor hours. In the field, that’s lost time and lost money. And for municipalities, it often means frustrated residents and additional strain on already tight public works budgets.
The Boxlok solves this problem before it starts. By holding the valve box in perfect alignment around the valve operating nut, the Boxlok ensures access stays exactly where it should be—no matter how heavy the backfill or how rough the terrain. Its non-load bearing, snap-on design is compatible with most AWWA buried valves, installs in seconds, and requires no digging or disassembly. With the Boxlok, contractors and municipalities can eliminate rework, improve project outcomes, and deliver reliable, professional results every time.

“One of the re-occurring challenges was that I was unable to get my key on many of the newly installed valves and valve boxes. These were added to my punch list for the land developers, and they would send the contractors back to the jobsite to dig the valve boxes up to get them re-centered over the hub of the valves. The cause of this costly redo was due to the common practice of dumping the backfill out of the front loader of a backhoe which pushed the bottom of the valve box against the op nut. In searching for a solution to this challenge that was occurring too often on new water main installations I found a valve box alignment device called the Boxlok by EMMA SALES. With 48 years (and counting) working in the water Industry, I know the need to install valve boxes correctly the first time, no one can afford to do things twice. For valve box alignment, Boxlok is the Solution!”

Manatee County, Florida uses the Boxlok designed for 6” PVC Riser Applications (Boxlok-3, Boxlok-4, and Boxlok-K3). Manatee County has been using the Boxlok since 2015.
"The Greater Cincinnati Water Works (GCWW) began using the Boxlok in 2005 on a trial basis. After a couple of projects, the GCWW found the Boxlok performed superbly and made it a standard requirement on the installation of all valve boxes whether in paving or soil. The savings that will be realized over the years moving forward will be tremendous as repair crews will no longer be called upon to straighten shifted boxes. The Boxlok is an excellent and reliable product."
