| Latch and Trunion | ||
| Ideal when fast detachment is required. The clamp is released with a flip of the thumb, eliminating the usage of any tools. The spring loaded 1/4-20 bolt absorbs thermal expansion in the fastened position. |  |
|
| Hinges | ||
| Used when a mica heater band has two sections. A piano hinge is incorporated on one side of the heater, while the other side can have any kind of clamp. |

| Spring-loaded barrel nuts | ||
| Independent straps, built-in barrel nuts and spot welded straps can have longer screws with incorporated die springs. These springs help to keep the mica band heater tight during thermal expansion. Only available in 1/4-20 screws |  |
|
| Clamping pads | ||
| Mostly used in two section partial heaters. When an obstruction prevents the usage of a complete mica band heater, it becomes necessary to create a large gap and fasten the heater to the cylinder on both sides of the gap. It is not advisable to have clamping pads on both sides of the same section of a mica band heater, because thermal expansion might detach the heater from the cylinder. |  |
