TO-185 Door Closer
The TO-185 Door Closer is a heavy-duty surface-mounted closer shown in the Tongguan catalog for wide and heavy project doors. It supports 1000-1700mm door widths and 80-110kg bearing weight, with two-stage adjustable speed control, 180 degree maximum opening angle and non-hold-open operation.
What buyers need to know first
Hardware buyers usually compare door type, opening size, fire rating, finish and access-control compatibility before asking for price.
Heavy-Duty Door Range
TO-185 is the heavier closer shown in this catalog section, with a listed maximum door leaf width of 1700mm and available bearing weight of 80-110kg.
Regular Arm Installation
The catalog application notes describe regular arm mounting on the pull side as the most power-efficient door closer application, with frame, door and ceiling clearance to be considered.
Top Jamb Installation
For push-side mounting, the top jamb application is presented as an alternative where exterior-wall doors swing out of a building, subject to frame projection and reveal depth.
Parallel Arm Installation
The parallel arm application mounts on the push side and keeps the arm assembly nearly parallel with the door, commonly used where reduced hardware projection is preferred.

Frequently Asked Questions About Door Hardware
What types of door hardware can SNRIDA supply?
SNRIDA can supply door hardware across several catalog groups, including panic exit devices, door closers, floor hinges, locks, handles, patch fittings and matching accessories. Each product page lists the catalog series, the door applications it is shown for, and the available material and finish options. Buyers should review the relevant product page for the model in scope before sending a quotation request.
Can door hardware be matched with different door types?
Yes. The hardware models in the SNRIDA catalog are reviewed against door type, leaf configuration, opening size, material and finish to confirm matching. Buyers should share the door type (for example single leaf, double leaf, wood, metal, fire exit or security door), the leaf dimensions and the planned finish so the export team can confirm the correct hardware selection before production.
What information is needed for a hardware quotation?
Please provide the product name or slug, the quantity, the door type and leaf dimensions, the preferred model and finish, the destination country, and any project drawings or hardware schedules that already exist. If the hardware is being matched with a specific door, fire door or security door order, please mention the related project reference so the hardware quotation can be confirmed against the same configuration.
Can hardware openings or installation details be prepared before shipment?
Yes. Thru-bolt positions, opening direction, hold-open or non-hold-open selection and other installation details can be reviewed against the approved drawings before shipment. Buyers should confirm the hardware model, opening direction, hold-open requirement and any on-site installation constraints before production so the configuration is built in from the start.
Can SNRIDA provide available certificates or test reports where applicable?
Depending on the project requirement and the specific hardware model selected, SNRIDA can provide product specifications, technical drawings, packing details and available certificates or test reports where applicable. Buyers should confirm required documents with their contractor, consultant or customs broker before shipment.
What should buyers confirm before ordering door hardware?
Buyers should confirm the hardware model and series, the door type and leaf dimensions, the finish tone, opening direction, hold-open or non-hold-open requirement, the accessory package (cylinder, trim, lever, arm type, mounting accessories) and the destination market. Production is started only after the configuration is approved against the project drawings and the related door order, if any.
