Recently we load tested several of our hinges. We secured the tested hinge to a pair of mount blocks, fastened one mount block to a counter and strapped a steel bar to the other mount block. We then hung weights on the steel bar at various distances from the center link to estimate sustained inch/pounds for each tested hinge. For most of the hinges, we took them to catastrophic failure, i.e., the center link snapped. Accordingly, while the hinges were able to withstand certain weights, we do not recommend stressing the hinges to near their failure point. The chart below displays the data we recorded:
| Hinge | Sustained Weight | Failure Weight |
| HCTH-2S-180 Family | 257 inch/pounds | 287 inch/pounds |
| HCTH-3S-180 Family | 523 inch/pounds | Not taken to failure |
| HCTH-44S-180 Family | 263 inch/pounds | 293 inch/pounds |
| HCTH-4S-180 Family | 523 inch/pounds | 537 inch/pounds |
| HCTH-5S-180 Family | 823 inch/pounds | 837 inch/pounds |
