The LiMAR® Sure-Trip Jar is a simplified Spring Jar alternative, specifically optimised for routine applications or scenarios where a known applied impact force will be sufficient in recovering downhole flow control devices, activating SSD’s, etc.

With a range of colour-coded Power Springs
to choose from, the Sure-Trip Jar is focussed
on reliably delivering a consistent and assured jar impact. Faster redress, compact design and more resilient in high debris environments, the simplicity of the Sure-Trip Jar means less components and less complexity resulting in a direct cost saving compared to Adjustable-type Spring Jars.
