Square Filter Holder for 86mm Lenses
This Urth holder accepts up to two 100mm square filters and an adjustable polarising filter. It mounts directly to lenses with an 86mm thread and can be adapted to other diameters using additional adapter rings. The system is built for photographers who want a modular filter setup without committing to a single lens size.
Magnalium Build and Sealing Gasket
The holder body is made from lightweight magnalium alloy, balancing rigidity with portability for field use. An in-built sealing gasket sits between the holder and adapter ring to block stray light from entering the stack. No active cooling or power draw is involved, so the accessory operates silently and adds negligible weight to the lens.
CPL Slot and Adapter Ring Included
A dedicated slot holds an adjustable circular polariser independently of the square filter stack, letting you rotate the CPL without disturbing graduated or ND filters. The package supplies the main 86mm adapter ring that locks the holder to the lens. Additional adapter rings for other thread sizes are sold separately, so the core kit covers only the 86mm fitment.

Questions about this item
How do I attach the holder to my 86mm lens, and what step often gets missed?
Screw the supplied adapter ring onto the 86mm front thread, then slide the holder onto the ring until it clicks; forgetting to align the locating pin leaves the holder loose.
Which parts will need replacement after extended outdoor use?
The in-built sealing gaskets can degrade from UV and grit, and the CPL slot’s rotating mechanism may stiffen; both are serviceable items.
What is the first limitation I will hit when stacking filters for long exposures?
The holder accepts only two 100mm square filters at 2mm thick each; adding a third causes vignetting on wide-angle lenses.
