# CST/berger 57-VMOUNT Wall and Ceiling Mount with 5/8 x 11 Female Thread
**$55.00**
Overview
The CST/berger 57-VMOUNT Wall and Ceiling Mount delivers a dedicated vertical reference solution for interior contractors working in space-constrained environments. This professional-grade mounting bracket features a precision-machined 5/8 x 11 female thread that accepts standard rotary laser levels, line lasers, and optical instruments, projecting stable plumb lines for drywall installation, electrical rough-in, cabinet alignment, and drop ceiling grid layout. The V-shaped clamp design securely attaches to ceiling grid T-bars, wall studs, door frames, and temporary bracing without penetrating finished surfaces. By eliminating floor-based tripods from congested work areas, the 57-VMOUNT reduces setup time by 40-60% while preventing accidental contact that causes recalibration delays. The corrosion-resistant steel construction withstands repeated field use across multi-unit residential builds, commercial tenant improvements, and institutional renovation projects where vertical accuracy directly impacts material waste and schedule performance.

Job Applications
- Drop Ceiling Grid Installation: Clamps directly to main tee runners or wall angles, projecting plumb lines to floor layout marks for perfect grid alignment without crawling underneath partially installed ceilings to verify measurements.
- Multi-Story Plumbing and Electrical Chases: Mounts to temporary cross-bracing in open chases, transferring vertical reference lines through multiple floors for stack alignment—critical when coordinating drain waste vent systems and electrical risers before drywall closes access.
- Full-Height Drywall Installation: Attaches to top plates or engineered lumber headers, creating continuous plumb references from ceiling to floor that eliminate cumulative error in 12-16 foot wall assemblies common in commercial and institutional construction.
- Kitchen and Millwork Cabinet Runs: Secures to upper cabinet mounting rails before installation, projecting alignment lines to base cabinet locations below—ensures vertical door reveals match across 10-20 foot runs where even 1/8" deviation creates visible alignment issues.
- Elevator Shaft and Stairwell Layout: Mounts to scaffolding cross-members or temporary platforms in vertical shafts, establishing plumb references without ground-based setups that obstruct material staging and worker movement in these confined high-traffic zones.
- Interior Window and Door Frame Alignment: Clamps to installed door headers or window bucks, verifying plumb before jamb installation—prevents the costly rework that occurs when rough openings shift during framing and framers have already moved to the next phase.

FAQ
- What's the maximum weight this mount can safely hold?
- The 57-VMOUNT is rated for instruments up to 8 lbs when properly secured to structural elements. Most rotary lasers weigh 4-6 lbs, providing a comfortable safety margin. Always verify the mounting surface can support the combined weight and vibration from nearby work activity. Suspended ceiling grid requires additional support blocking for loads exceeding 5 lbs.
- Can this mount attach to standard 15/16" drop ceiling grid?
- Yes. The V-jaw clamp range of 0.5" to 2.5" accommodates standard 15/16" grid tees, heavy-duty 9/16" grid, wall angles, and 2x4 wood framing members. For narrow grid profiles, position the clamp at tee intersections where double material thickness provides better grip security. Avoid mounting to cross-tees supporting acoustic tile weight without adding temporary support.
- Will this work with laser levels from other manufacturers?
- The 5/8 x 11 female thread is the construction industry standard adopted by virtually all professional laser manufacturers including Bosch, Dewalt, Leica, Topcon, Spectra Precision, and Stabila. Verify your specific instrument has a 5/8 x 11 male thread base—some compact consumer models use proprietary mounting brackets incompatible with standard threads.
- How do I prevent the laser from rotating after mounting?
- After threading your laser onto the mount, hand-tighten until resistance is felt, then advance an additional quarter-turn. Most professional lasers include rotation locks or detent mechanisms that engage at this point. For instruments without rotation locks, apply a small piece of adhesive-backed foam between the laser base and mount body to increase friction. Always perform a tap test—firmly strike the mounting surface and verify the laser doesn't shift before beginning layout work.
