Rotary Butterfly Draw Latch with Special Protective Ramp

Retrofit your B&W Bike.box 1 with these positive latching rotary locks! The old pop-up latches are sometimes hard for the TSA to close properly after inspection, so these rotary latches will add peace of mind when travelling with your expensive bike.

Draw latches are extremely versatile latches that can be used anywhere, from equipment cases and toolboxes to RVs and garbage cans. High working loads, convenient mechanical advantage, and compact size are common advantages that make rotary draw latches a good choice for co-planar applications where space and strength are important functional considerations. There are dozens of names these locks go by: butterfly latches, wing locks, cam latches, rotary locks. Use the dimensions and specifications in the diagram below to see if these will fit your application.

These are surplus latches which are used in the construction of B&W Bicycle and Tool cases. You can find more about the company here.

These latches are compatible with the K4 Southco latches item number K4-2359-07 (K4-2338-07 is the standard keeper).
Hex head design provides added strength and allows latch to be tightened with hex wrench. Spring loaded anchor plate compensates up to 4mm (.156") for misalignment

We are selling each latch with a special one-piece moulded ramp to protect the lock from sliding and baggage handlers. You can use it or not, depending on your application.
We also include a specially formed keeper plate, which is designed to mount flush on the edge of an aluminum profile, as shown in the pictures.
If you prefer a flat, standard keeper plate (K4-2338-07), we have some in stock and can swap them out 1:1 for the black, formed keeper, which will be the default shipped, if we don't get an email from you. Take a close look at the high quality construction of this item. All the edges are smooth and sharp edges have been rounded and polished.
