About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

5 Insightful Analyst Questions From W.W. Grainger’s Q2 Earnings Call

GWW Cover Image

W.W. Grainger’s second quarter saw revenue climb as the company navigated a challenging environment, but the market responded sharply negatively to the results. Management highlighted that tariff-related inventory accounting and price/cost timing issues weighed on profitability, particularly through LIFO (last-in, first-out) inventory impacts. CEO Donald Macpherson pointed out that demand from contractor and healthcare customers was a bright spot, offsetting muted trends elsewhere, while CFO Dee Merriwether emphasized that most margin pressure was transitory, stemming from accounting rather than operational weaknesses. The leadership acknowledged that underlying operations would have shown more robust earnings growth without the LIFO headwinds.

  • EPS (GAAP): $9.97 vs analyst expectations of $10.06 (0.9% miss)

While we enjoy listening to the management's commentary, our favorite part of earnings calls are the analyst questions. Those are unscripted and can often highlight topics that management teams would rather avoid or topics where the answer is complicated. Here is what has caught our attention.

Our Top 5 Analyst Questions From W.W. Grainger’s Q2 Earnings Call

  • David Manthey (Baird) asked about the LIFO accounting impact, and CFO Dee Merriwether clarified that most of the margin pressure was due to LIFO, not operational weakness, and that underlying EPS growth would have been higher on a FIFO basis.
  • Thomas Moll (Stephens) questioned the rationale for delaying price increases until September, to which CEO Donald Macpherson responded that maintaining a predictable schedule supports customer relationships and long-term loyalty.
  • Chris Snyder (Morgan Stanley) pressed on why Grainger was not seeing the same disruption-driven tailwinds as during COVID, and Macpherson explained that the current environment lacks major supply shocks, though Grainger is still gaining share.
  • Ken Newman (KeyBanc Capital Markets) inquired about price elasticity and customer volume as tariffs are passed through, and Macpherson replied that demand is expected to be soft, but Grainger’s approach is aligned with competitors, and confidence remains in price realization.
  • Patrick Baumann (JPMorgan) asked if margin expansion could resume in 2026 as LIFO impacts roll off, which Merriwether and Macpherson agreed was reasonable barring further unexpected changes.

Catalysts in Upcoming Quarters

Looking ahead, the StockStory team will focus on (1) the pace and effectiveness of September pricing actions in offsetting tariff-driven cost increases, (2) whether gross margin begins to recover as LIFO impacts cycle out, and (3) ongoing growth and profitability in the Endless Assortment segment, especially as Zoro and MonotaRO execute on digital and assortment optimization. How Grainger adapts to evolving competitive and supply chain pressures will also be closely watched.
