Nigel,
   These are standard HP 1/2 rack units.  The rubber bezel around the 
front and back peel off.  HP (Agilent, now Keysight) makes a Link Lock 
Kit 
<http://www.ebay.com/itm/HP-Agilent-Lock-Link-Kit-5061-5458-/291271152251?pt=LH_DefaultDomain_0&hash=item43d11d127b> 
to connect the units. The finger piece mount in the slots in the side of 
the front bezel and lock together. The lock pieces strap the rear square 
frame posts together.  Add the 2U (each 'U' is 1-3/4") rack mount 
flanges and you're good to go.

Mike
