Guide Comb Set for 40mm T-Blade Trimmer

VALLNEI Guide Comb Set is an eight-piece collection of precision snap-on guards designed to fit 40mm T-blade trimmers (including many Wahl models) for consistent hair and beard length control from 1.5mm to 13mm.

Upgrade your trimming toolkit with replacement guards engineered to match original equipment fit and function. These eight guards cover common short-to-medium lengths so you can shape fades, maintain stubble, or trim a beard with repeatable results. Built from impact-resistant plastic, they’re intended for regular home or professional use on compatible detachable 40mm T-blade trimmers.

Which trimmers will these guards fit?

These guide combs are made for 40mm T-blade systems and are compatible with many Wahl detachable T-blade trimmers. Before buying, check that your model uses a detachable 40mm T-blade to ensure a secure fit and reliable performance.

• Works with several Wahl models including 9818, 9864, 9888, 9898, 9816, 9867.
• Designed to match original equipment attachment points and snap-in geometry.
• Not suitable for non-T-blade or blade widths different than 40mm.

How precise are the lengths and what sizes are included?

The set offers eight clearly graduated lengths for precise trimming control, from close stubble to short clipper lengths. Each guard corresponds to a common cutting length so you can repeat styles reliably without measuring each pass.

• Included sizes: 1/16" (1.5mm), 1/8" (3mm), 3/16" (5mm), 1/4" (6.5mm), 5/16" (8mm), 3/8" (9.5mm), 7/16" (11mm), 1/2" (13mm).
• Graduated steps support blending, layering, and controlled fade transitions.
• Color-free, marked sizing makes selection straightforward during trimming.

Are these guards durable and easy to use?

Yes — the guards are molded from impact-resistant plastic to resist cracking and warping under regular use. Installation is tool-free: snap the chosen guide onto the trimmer T-blade and remove it the same way when switching sizes.

• High-strength plastic construction for long-term home or shop use.
• Secure snap-fit keeps the guard steady for even cutting without wobble.
• Simple attachment and removal — no screws, clips, or extra parts needed.
