The Ballistic Dual Frame Link Mount is engineered to mount to the frame for a compact self-jigging design eliminating the need for a cross-member in many cases.
Cut from 1/4" steel with an inner mounting width of 2 5/8".
Bolt hole diameter is 9/16".
They are made of 1/4" metal and appear to be very strong but I have not mounted them yet and I am only giving this review so I will stop getting emails about leaving a review.
Once I order it They shipped it the next day
