of the strips, by providing the strips with suit

provided with a pair of such openings. As shown,
20 the openings ll] of the tacking strip l2 of Fig. 1',
of‘the tacking‘ stripv l3’ of Fig.. 2, ofr'the» tacking
strip I of Fig. 3 and of the: tacking strip. ll of

the present strips lie- in’ the“ same‘ cross plane
and are-spaced apart‘ a su?icient distance to per

strip lying therebetween. In the tacking’ strip

Tosecure the present tacking, strips to metal

upper edge portion: [1a of. the sidewalls of‘ such
holder. As shown, the side walls‘ of; the holder

and H, with tacking‘ strips-secured therein, may
65 be easily and conveniently secured, by spot-weld
ing or the like, to any metal’ surfaces which are
to be covered with upholstery or the like.
Another method of‘ securing the present tack
ing strips to metal surfaces is to provide such
70 surfaces with suitable clamping tongues, such as
the. tongues 22 of Fig. 5. As here shown, two sets
of tongues 22 are struck up from the metal mem
ber 23, for clamping, engagement with. both sides

nal groove which extends upwardly from the bot 20
tom corner portions forming a substantially con
cave bottom surface and; generally rounded cor.
ners between the bottom: and: side surfaces, the
grooves in the sides. being relatively narrow with
respect to the groove in the bottom and being lo 26
