V-Lock Hard Top Mount Instructions

Rocket Shade™ V-Lock Hardtop Cap Mount Installation Guide

For solid attachment to top-bolted hardtop surfaces
(Ideal “no-drilling” solution for T-Tops and Runabouts)

Overview

The V-Lock Hardtop Mount provides a simple, secure attachment for extending Rocket Shade coverage over the bow or cockpit area on boats with cap-attached hardtops. Follow these steps for accurate placement and long-term durability.

Required Tools

  • Tape measure and long straight edge
  • Torx driver (included with Rocket Shade system)
  • Allen wrench or socket set

Parts Provided by Customer

  • Stainless-steel bolts of proper length (only if existing hardware must be replaced)

 

Installation Steps

1.      Select Mounting Locations

·         Choose positions that provide the best shade coverage — typically on either side of the hardtop, above the bow or cockpit area.

2. Determine V-Lock Separation and Angle

  • The Rocket Shade mounting tube connects to two V-Locks attached at existing hardtop mounting points.
  • Measure the center-to-center distance between these mounting caps and ensure that the cantilever tube will extend at least 8 inches beyond the hardtop edge for adequate overhang.
  • Using a long straight edge, span the surface between the two mounting points to assess hardtop flatness.
    • Slight curvature is acceptable — this system accommodates up to 1.5° of surface curve.
    • If curvature exceeds this tolerance, contact Rocket Shade support for optional custom-angled mounts.

3. Attach the V-Lock Bases

  • Reuse the existing bolts.  If this does not work, replace them with marine-grade stainless bolts of suitable pattern and length.
  • Install the provided rubber isolators between the mount base and the hardtop surface to protect the finish and damp vibration.
  • Each pair should include one V-Lock base with integrated spring pin for secure locking and easy release.
  • Tighten bolts evenly with an allen wrench or socket set — do not overtighten.

4. Configure and Test the Mounting Tube

  • On the 48-inch aluminum mounting tube, position and fasten the V-Lock inserts to match the installed base spacing.
  • Test the lock-in and removal function for smooth engagement.
  • Tighten all Torx screws securely once alignment is confirmed.
  • Attach the mounting tube to the cantilever assembly, replacing any rod-holder insert if previously used.

5. Final Adjustment

·         Mount the Rocket Shade cantilever and verify locking engagement. Adjust the tilt and orientation for best shade coverage.

Important Notes

  • Always verify alignment before forcing attachment — misaligned V-Locks may hinder cantilever system installations.
  • Check mounts periodically for tightness, especially after long travel or exposure to vibration.
