[Latest Technologies] Vacuum heat treatment leads to improved cutting performance and durability. Automated manufacturing and quality control ensure precise manufacturing tolerances and consistent performance across all chainsaw chains produced. [Sharpness and Longevity] Japanese industrial hard chrome plating for increased sharpness. Hardening technology of chainsaw chains significantly increases their wear resistance and lifespan, allowing for more efficient and long-lasting cutting. [Safety] Low kickback design and ANSI standard-compliant ensure safety. Lubrication systems reduce friction and wear, ensuring a smooth and efficient cutting operation, which contributes to enhanced safety by minimizing the risk of chain derailment or breakage. 16 Inch Chainsaw Chain 3/8" LP Pitch .050'' Gauge 56 Drive Links Fit POULAN 220, 221, 222, 260, 400E, 1420, 1425, 1625, 1630, 1800, 1950, 2000, 2025, 2050, 2055, 2075, 2150, 2175, 2250, 2300, 2375, 2450, 2550, 3416, 3516, 3516AVX, 3816 Fits these chainsaw models with a 16" bar: Craftsman:CMECS600, S160, S165, CMECS600; Earthwise CS30116, CS33016; Homelite ZR43100, UT43123; Husqvarna 240, 135, 120 Mark II Fits Makita UC4051A, XCU03, XCU04CM; Oregon CS1400; Poulan PR4218, PL1416, PL3816; Remington RM1645; Ryobi RY3716; Sun Joe SWJ701E; Wen 40417 BYANE 16 Inch Chainsaw Chain 3/8" LP Pitch .050'' Gauge 56 Drive Links Low-kickback Fits Poulan P3816, Craftsman CMECS600, S160, S165, CMECS600, HOMELITE, Ryobi, S56 (3 Chains)
