This particular design of 

 ball-bearing vent hanger is 

 bolted to both the rafter and 

 purlin, taking the placi of 

 the regular purlin knee.

Here is our Standard Ball-bearing Hanger all apart. 

 It's built almost like a watch. But it has ti.e strength. 

 It stands the racket.

FOR a long time we had been using a ball-bear- 

 ing on some of our ventilaiiug gears. 



Then we equipped a shaft hanger witli it, and can't 

 help wondering why it wasn't done long before it 

 was done. 



Of course, it makes the apparatus run easier -a lot 

 easier. 



It does cost a bit more than the old hanger, but 

 what of it? 



If it takes a lot of the lug and tug out of the venti- 

 lating, what does the (luestion of a little extra on 

 the cost amount to? 



But don't for a minute compare this ball-bearing 

 hanger with those that have been rushed on the 

 market in competition. 



Look at the photograph of the parts shown above, 

 and you will see how it is not skimped in any way. 

 In fact, it's made just like a bicycle bearing, or as 

 any other dependable ball-bearing is made. 



Although there seem to be quite a few parts, its 

 construction is simplicity itself. 



They all go together easily and fit into a surpris- 

 ingly compact space. 



If you still prefer the old hangers, we have them. 

 But once you have equipped a run of ridge sash 

 with the ball-bearing ones, you will never go back 

 to the old. 



This ball-bearing hanger, in combination with our 

 counterbalance gear, cuts elbow grease down to 

 almost no grease at all.
