is further illustrated by way of the example set out below reference is made to fig5 which illustrates an existing lining 50 mounted to a roof plate 52 of a describe furnace or device to which lining secured by means of a stud 54 and washer 56 the existing lining was made up of four layers of ceramic fiber blanket having a combined thickness on the order of 6 in a ceramic fiber securing device 58 according to the present invention was threaded through the existing fiber layers 50 leaving only a straight portion 60 protruding generally coaxial with the stud 54 the ceramic fiber securing device had the following approximate dimensions ______________________________________diameter of helical portion 4 in approx 10 cm pitch of helical portion 1 1 4 in approx 3 cm height of helical portion 7 in approx 13 cm length of straight portion 3 in approx 7 5 cm cross section area 1 2 in u00d7 1 4 inc approx 3 mm u00d7 6 mm material type of stainless ______________________________________ after installation of the ceramic fiber securing device 58 a 10 lb approx 4 5 kg weight was suspended from the straight portion 60 no indication of undue strain or 34 pulling out 34 of the ceramic fiber securing device was observed as interanchor spacing is generally from 12 34 to 18 34 and as a new lining will typically be on the order of 2 in thick with a density of about 8 lb per cubic foot the amount of force typically carried by each ceramic fiber securing device will generally be considerably less than 10 lb in the present.
