The Streamlight 88051 is designed so that when you sit down, you dont get poked in the ribs by your flashlight. The spring-loaded interior wall holds the flashlight in place and compensates for different body diameters. Fits a standard web duty belt with a 3-inch width. The tactical holster can be inverted, and your flashlight will stay in place due to the spring-loaded wall. Made with a lightweight, super-tough nylon construction. The tactical holster is only compatible with: ProTac HL, ProTac HL 3, PolyTac, PolyTac HP, TL-2, TL-2X, Strion, Strion LED, Strion HL, Strion HP, Night Com, Night Com UV, and Twin Task 2L (lanyard removed)
