Review on 🔒 JQuad Trailer Door & Ramp Locking Hasp - 4" Mounting - Cam Lock Latch Keeper - Zinc Alloy Construction by Jerry King

model with 3-3/4" hole spacing, it doesn't fit Master Hidden Shackle 6271 because of the lock cleat The holes in the rosette are not far enough away from the lugs (too close to the main body) of the rear of the Master Lock because the distance between the two lugs is too large at about 4mm (nearly 3/16 inch) and the curved edges of the rocker arm lugs exacerbate the fit problem . Also, round mounting holes are not suitable for carriage bolts. The square head of the 1/4" carriage bolt does not fit in the mounting hole that is the hinge of the moving part of the bolt. The other mounting hole is too big to hold the square carriage bolt. It would have been so easy to engineer it to avoid these issues I'll be returning it and looking elsewhere.
