Frequently Asked Questions
A comfortable height for placement of a handleset is 40" above finished floor level. How should a handleset be located in relation to the strike side of the door? 3" is an acceptable distance from the strike side of the door to the handleset centerline. What is the weight capacity of CHMI 200 Series hinges? Weight should not exceed 50 lb. per hinge. Remember to consider the added weight of any handlesets, towel bars, etc. that are mounted to a door when calculating the required number of hinges for that door. How many hinges may be used to mount a door? For wall-mounted doors (excluding GWHB202 buttress hinge), a maximum of 2 hinges shall be used. This restriction is due to mounting surface conditions that can be unpredictable and unreliable when attempting to plumb hinges (i.e. hinge-to-hinge alignment is more difficult to achieve with an uneven surface). Using a third hinge on a wall-mounted door increases the chances for misalignment due to this unevenness. For glass sidelight-mounted doors, a maximum of 3 hinges shall be used. Be sure that the glass panels are not warped as this also will result in misalignment. What are the maximum allowable door widths when using the 200 Series hinge? For 3/8" thick glass, a maximum door width of 36" shall be used. For *" thick glass, 30" maximum width shall be used. What are the weights per square foot for both 3/8" thick and *" thick glass? 3/8" thick clear tempered glass weighs approximately 5 lb. per sq. ft. *" thick clear tempered glass weighs approximately 6.5 lb. per sq. ft. When using the GGHN0135 neo-angle hinge, how should the door and sidelight hinge-side edges be cut? The hinge-side door edge must always be straight-cut. The hinge-side sidelight edge must always be back-mitered at 45 degrees. Is it o.k. to use wall-mount hinges other than the GWHB202 buttress hinge to mount a door to a buttress wall? The GWHB202 is designed to be used in conjunction with the CHMI in-line and neo-angle glass-to-glass hinges. The GWHB202 produces a gap between the glass edge and the mounting surface that matches that of the glass-to-glass hinges. This is achieved when the sidelight edge is matched up to the vertical end face of the buttress wall. Other wall-mount hinges such as the GWH200 and GWH201 produce a gap that is larger. If used, they would create an out-of-alignment condition with the upper glass-to-glass hinge(s). Can the GWHB202 buttress hinge be used if the end face of a buttress wall on a shower unit is oriented at an angle other than perpendicular to the plane of the door with the door in the closed position? The buttress hinge will not work with this configuration. If the buttress hinge were mounted at an angle not perpendicular to the door, the pivot point of the buttress hinge would not line up with the pivot point of the glass-to-glass hinge above. It is possible to align the pivot points if the buttress hinge is rotated inward and moved to the inside vertical edge of the buttress wall. Consult our customer service department for further details on this. Another option is to add a 6" min. width sidelight in-line with the door and hinge between this sidelight and the door with a GGH200 in-line hinge. This added sidelight would have a mitered vertical edge that would butt up against the buttress wall and the sidelight on top of the buttress. These options should be considered at the design stage, not at the installation stage when it is too late to change glass sizing and positioning. Can the closing "pressure" of the CHMI 200 Series hinge be adjusted? If the door is closing with a "slam" or torques the sidelight too much, one or more of the internal hinge springs may be removed to soften the closing action. An instruction sheet is available from our customer service department on this procedure. The solution may be as simple as adjusting the vinyl sweep on the bottom of the door so that it drags more on the curb. Also, a polycarbonate/vinyl strike mounted to the vertical edge of the strike sidelight will help soften the impact and will help produce an air cushion as the door approaches the closed position. Finally, the problem may lie in the orientation of the internal hinge pin. In its standard position, the pin allows the hinge to index into its closed position at 90 degrees (in-line). If the pin is flipped or rotated, the hinge will lock into an alternate position 13 degrees offset from 90 degrees. This effectively orients the hinge/door inside or outside of the standard in-line orientation by 13 degrees. If the pin is in the 13 degree offset position oriented inward, the door will close with more pressure, when used with a door stop or strike. Can CHMI towel bars be mounted to surfaces other than glass? Towel bars can be mounted to any surface that an anchor bolt can be screwed into. This includes but is not limited to: wood, gypsum, and plastic wall anchors in tile or marble. This is achieved by first screwing the machine thread end of the anchor bolt into a CHMI "blank" conehead bolt. Two of these custom conehead bolt/anchor bolts are then fastened into the mounting surface at the appropriate center-to-center distance until the base of the conehead is flush with the mounting surface. A "conehead both ends" towel bar is then fit over both exposed heads and the set screws are tightened down against the conehead. NOTE: this installation method with the CHMI towel bar is not to be used as a handicap grab bar. Custom fabrication: Is there any way to compensate for an odd-angle transition between glass panels where the standard 180° or 135° hinges will not work? The simplest solution to this problem is to flip the hinge pin end-for-end so that the hinge indexes into the 13 degree offset position. This, of course, can be used only if the angle between panels is 135° plus or minus 13, or 180° plus or minus 13. A door stop can then be applied to the strike sidelight and the offset pressure position of the hinge pin will push the door into the strike. For doors that swing in and out where a door stop is not desired, a custom pin can be ordered that is machined to a specified angle. Custom-angle glass clips and interior channel clips can also be ordered. Can a hinge be positioned so that the outside face of the hinge coverplate is flush with the outside vertical face of the wall that is being mounted to? A custom offset hinge mounting backplate is available for this application where all four mounting screws are on the interior of the shower unit. Is there a hinge that can be used in wall-mount situations where the curb below the door is not perpendicular to the hinge mounting surface? The standard glass-to-wall hinges when used with a custom-angled
pin work well in this case. Also, a custom backplate can be produced
that will accomodate a specified angle.
