1.5" Precision Spacer for Metabones Adapters | Extended Clearance Block

The Hejnar Photo 1.5-Inch Precision Spacer Block is a dedicated structural correction component custom-designed to address height limitations on professional Metabones lens adapters. Engineered to install securely between the adapter body and its mounting foot, this high-stiffness riser block delivers essential physical clearance. It completely resolves hardware spatial constraints when trying to deploy wide-diameter lenses, large tripod heads, or vertical camera L-brackets on professional tripod and monopod platforms.

Quick Overview & Key Features

• Dedicated 1.5" Elevation: Provides a robust 1.5-inch vertical riser profile, lifting your optical setup to clear wide quick-release clamp platforms and pan knobs.
• Critical Height Clearance: Eliminates structural bottlenecks, preventing large-barrel telephoto zoom lenses or wide camera L-brackets from physically striking support gear.
• Anti-Twist Alignment Channels: Precision-milled geometric seating tracks completely eliminate shifting, twisting, or mechanical play under heavy torque loads.
• Uncompromised Structural Rigidity: Solid unibody metal block design eliminates the flex, wobble, and play associated with stacking crude universal plates or washers.
• Universal Adapter Compatibility: Custom-machined block profile engineered specifically to index perfectly with the baseline structural footprints of professional Metabones smart adapters.
• Premium US Craftsmanship: Precision CNC-machined from a solid block of aircraft-grade 6061-T6 aluminum.
• Durable Hard-Coat Finish: Treated with a satin black hard-coat anodized surface layer for advanced resistance against scuffs, scratches, and harsh outdoor field elements.
• Complete Assembly Hardware: Supplied with high-tensile, corrosion-resistant stainless steel mounting screws custom-lengthened to ensure absolute structural safety.

Product Description

The premium Hejnar Photo 1.5-Inch Precision Spacer Block for Metabones solves a frustrating and persistent clearance design bottleneck commonly encountered by landscape, wildlife, portrait, and event photographers deploying adapted lens trains. The factory foot layout on original Metabones adapters sits exceptionally close to the primary lens axis. Consequently, when trying to lock your camera system onto wide tripod platforms, large monopod tilt-heads, or universal Arca-Swiss quick-release receiver clamps, the bulky barrel of fast-aperture lenses or the horizontal wing of a camera L-bracket will physically bottom out against the support hardware. This prevents a clean lock, jams the plate slider slots, and puts dangerous leverage strain on your lens mount.

This custom-engineered 1.5-inch spacer block provides a permanent, elegant physical fix. Installed directly between the adapter body and your existing plate or replacement foot, it delivers the exact vertical lift required to let wide optics and corner brackets clear your support equipment cleanly. Because close-up macro imaging and telephoto tracking place intense torsional stress on your gear joints, this block is built with precision index tracking channels that seat flush against the hardware. This design choice completely removes stack tolerance errors and dampens micro-vibrations, giving you an ultra-rigid connection that will not slip over time.

Bespoke-crafted in the USA from ultra-strong aircraft aluminum, this spacer ensures your optical center remains perfectly squared and true to your tracking axis. The kit includes extended high-tensile fasteners that pass cleanly through the spacer body to ensure deep, maximum-security thread engagement inside the adapter body. Finished with a rugged black hard coat built to withstand severe field use, this spacer block delivers the mechanical precision, safety margin, and lifelong reliability your camera rig requires.
