Before we introduced these neat suspension units, builders wanting to compensate or spring carrier wheels, pony trucks or tenders, had to make do with bushed-out, full-size hornblocks, or make their own arrangements...
The small size of our MiniBlox means they almost 'disappear' under tenders, and they're ideal for shallow-framed areas, where full-sized blocks would stick out like a sore thumb, or they simply wouldn't fit at all. The bearings themselves have a 2mm bore.
Also available, MiniBlox 'CSB' Carrier Tags - ideal for tenders - and a Drilling Jig to make the job easier.
