The whole specification includes every thing, but the most crucial part was missing, picture attached for those who are looking for such info, it would have been appreciated, if seller had responded to the question. ## Features - LOCK APPLICATION: Best used for vehicles, trailers, and RV hitch locks - EASE OF USE: Six locking positions provide maximum flexibility; Rekeyable cylinder offers keyed-alike convenience - DURABLE DESIGN: Water-tight cap protects trailer hitch lock from moisture and dirt - SPECIFICATIONS: Coupler lock adjusts from 9/16 in. to 2-3/4 in. length - INCLUDES: One trailer coupler latch lock, two keys ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001B0QBZ6 | | Best Sellers Rank | #74,955 in Automotive ( See Top 100 in Automotive ) #40 in Automotive Hitch Locks | | Brand | Master Lock | | Customer Reviews | 4.5 4.5 out of 5 stars (2,925) | | Date First Available | 6 August 2012 | | Item Weight | 113 g | | Item model number | 2847DAT | | Manufacturer | MASTER LOCK COMPANY LLC | | Manufacturer Part Number | 2847DAT | | Model | MASTERLOCK | | OEM Part Number | 2847DAT | | Product Dimensions | 17.27 x 10.16 x 2.54 cm; 113.4 g | | Special Features | durable, slim fit | ## Product Details - **Brand:** Master Lock - **Item dimensions L x W x H:** 17.3 x 10.2 x 2.5 centimeters - **Lock type:** Key Lock - **Material:** tpu - **Special features:** durable, slim fit ## Images ![Master Lock Trailer, Stainless Steel Adjustable Coupler Latch Lock, 2847DAT, 1 Pack - Image 1](https://m.media-amazon.com/images/I/71nk22trIRL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: what is diameter of the pin?** A: Diameter of the pin is approx. 9/32 inch..
