material of a thickness such that the fingers 52 can easily pass through the screen openings 30 as depicted in fig4 of the drawings it may be also preferable in some applications that the fingers 52 are bendable or otherwise manipulatable by one 39 s fingers to change their angular relationship with the arms for ease in fitting into the same holes as above indicated it is preferably that two or more of the arms 50 be present and that they are disposed in a laterally separated configuration at their outer terminal ends such that the weight of the device 10 is distributed to more than one specific area of the screen and that lateral sway and to some extent front to rear sway caused by a combination of wind as well as the back and forth lateral sliding movement of the screen 20 is minimized it is generally contemplated that the arms 50 be formed from a metal wire material and as previously indicated the lower ends 51 of the arms 50 proximate to the body 40 are attached thereto by any suitable method including a forced fit into holes machined or otherwise provided in the body upper surface 46 the embedding of the proximal ends of the arms 50 in the body as in a casting or hardening procedure or the adhesive connection thereto by conventional means such as glue also in order to better stabilize the device 10 the lower body surface 48 is provided with preferably a pair of downwardly and preferably inwardly extending legs 60 which in turn terminate in foot portions 62 the proximate upper ends 64 of the legs 60 are connected to the body 40 similar to the various means by which the arms 50 are.
