Mannial 20" Chainsaw Chain 3-Pack for Husqvarna & Stihl 3/8" .050" 72DL — Full-Chisel, Heat-Treated

Mannial 3-pack 20" replacement chains deliver professional-grade cutting performance for compatible Husqvarna and Stihl saws with a 3/8" pitch, .050" gauge, and 72 drive links.

If you own a 20-inch guide bar saw like the Husqvarna 455 Rancher or various Stihl models, these Mannial chains provide a ready-to-use, value-focused supply plus a compact sharpening kit. Each chain is built with a full-chisel cutter profile for fast, aggressive cuts and is heat-treated to resist stretching and wear. The bundle is intended for homeowners, landscapers, and pros who want dependable replacement chains and the tools to maintain sharp cutters on the job.

Which saws and bar sizes do these chains fit?

These Mannial chains are made for 20" (50 cm) guide bars with a 3/8" pitch and .050" (1.3 mm) gauge, using 72 drive links. They match many popular Stihl and Husqvarna models as listed by the manufacturer — always check your saw’s manual or the bar markings to confirm compatibility before installing.

• Designed for 20" guide bars (50 cm)
• 3/8" pitch and .050" gauge (1.3 mm)
• 72 drive links for correct sprocket engagement
• Compatible with many Stihl and Husqvarna chainsaw models

How do these chains perform compared to stock chains?

The full-chisel cutter profile provides faster, cleaner cuts through softwood and seasoned hardwood, while the heat-treatment process increases hardness and reduces stretch. Expect aggressive cutting speed and reliable feed when the chain is sharp, though full-chisel cutters do require regular maintenance to keep peak performance.

• Full-chisel design for rapid, efficient cutting
• Heat-treated and quenched for improved durability
• Optimized cutter geometry to reduce vibration and fatigue
• Requires routine sharpening to maintain cutting speed

What comes in the 3-pack bundle and how does maintenance work?

This kit includes three complete chains plus a compact sharpening kit so you can service chains between uses. The sharpener items allow on-site touch-ups that prolong chain life and keep cutting consistent, reducing downtime and replacement frequency.

• Three 20" chains (3/8" pitch, .050" gauge, 72 drive links)
• Sharpening kit: two 7/32" round files, one flat file, depth gauge, and handle
• On-site maintenance capability to extend chain life
• Cost-effective replacement supply for frequent users

Are there safety or installation tips I should follow?

Install and tension the chain with the saw powered off and the spark plug removed or battery disconnected. Use proper PPE—gloves, eye protection, and chainsaw chaps—and follow the saw manufacturer’s instructions for chain direction, tension, lubrication, and bar care. Regularly inspect for damage, missing rivets, or bent links before each use.

• Turn off saw and disconnect power source before changing chain
• Set correct tension and keep the bar and chain well-lubricated
• Use eye protection, gloves, and chainsaw chaps when operating
• Sharpen cutters with supplied tools to maintain safe cutting performance

Who this is for: This Mannial 3-pack is suited to homeowners who cut firewood, property managers maintaining trees and large shrubs, and professionals who need a cost-conscious supply of high-performance chains. If you run a 20" bar on a compatible Husqvarna or Stihl saw and prefer a full-chisel profile for fast, efficient cutting — plus the ability to service chains in the field — this bundle offers both replacement chains and the basic sharpening tools to keep them working reliably.
