This a mechanical system enabling one man only to lift the slate, anytime it is necessary to change the cloth or access to the table inside for maintenance.
Easy functioning: two jacks with gas struts inside the cabinet raise and lift the slate.
Zero consume: the system has neither battery nor it requires voltage connection. No maintenance is required.
Useful on tables of any size, it is particularly recommended on 8 and 9 foot tables, which have the heaviest slates.
