For everyday framing and electrical layout, a quality spirit level from Stabila (the 96-2 or Type 196 series) is accurate to within 0.5mm/m and holds calibration for years. For longer runs or one-person layout, a self-leveling laser like the Bosch GLL series or Klein 93LCLG gives you a continuous reference line across an entire room. Most pro electricians and framers carry both: a 48" spirit level for daily work and a cross-line laser for layout-heavy days.

Most commercial general contractors in the Houston metro require: ANSI Type I Class E hard hats (1500V rated), Z87+ safety glasses, ANSI A2 or A3 cut-rated gloves, high-visibility Class 2 vests, and steel-toe or composite-toe boots meeting ASTM F2413. For elevated work over 6 feet, fall protection (harness + lanyard) is required by OSHA. PPE specs vary by GC — always check the site-specific safety plan before showing up.

Line lasers (cross-line or 3-plane) project visible horizontal and vertical lines onto walls — ideal for interior work like tile, drywall, cabinets, and electrical box layout. Rotary lasers spin a single point 360°, projecting a continuous reference plane across a large area — used for grading, foundation work, and outdoor layout. For most interior trade work, a self-leveling cross-line laser like the Bosch GLL3-330CG is more practical.

Yes — Tool Mart stocks full-body harnesses, lanyards, self-retracting lifelines, and anchor points from MSA, 3M DBI-SALA, and Honeywell. For contractors building out a fall protection program for a crew, we can quote complete kits with the SRLs and harnesses matched to the work height. All gear we stock meets ANSI Z359 and OSHA 1926.502.
